Until now the initial renderpass layout wasn't set, resulting
in errors/warnings when using the renderpass. This PR sets the
initial and final renderpass to general so the code knows what
to expect.
In future this needs to be designed better as the layout will
change when used in as a framebuffer attachment, or presenting
on the screen.

This PR adds initial cube (array) support. Depending on how the texture
is used a different image view is created. When used as a framebuffer
attachment only a single side of the cubemap is attached. The image
view is attached as a 2d texture array. When used as a shader resource
the image view is a cubemap.
Also adds test cases to test both scenarios.

* opengl_context -> system_gpu_context. This is the operating system OpenGL,
Metal or Vulkan context provided by GHOST.
* gpu_context -> blender_gpu_context. This is the GPUContext provided by
the Blender GPU module, which wraps the GHOST context and adds some state.
* Various functions create/destroy/enable/disable both contexts, these have
just gpu_context in the name now.

When a file passed in from the command line failed to load,
blender would exit & save the quit.blend.
Resolve by adding a `do_user_exit_actions` to WM_exit_ex which is
false in backgrounds mode or when an error has occurred.

Callers to WM_exit needed to set G.is_break for a predictable exit-code.
This is error prone as G.is_break may be set based on the user having
pressed escape during event handling.
Instead, pass the exit code as an argument.
Although auto-focus only works between a single Blender instance's
child windows, this does include our own console and we don't want
that. Luckily fixing this only requires a single check for null -
because GetFocus() returns null to us for our console.

Previously, each GHOST Context instantiated its own Metal device
queue. Commands are only synchronized within a queue, this was the
root cause of a number of flickering issues which had previously
been worked-around with synchronization primitives.
New solution uses a shared queue to simplify dependencies and
alleviate possibility of stalls and bugs when resources are modified
or shared across separate GPU command queues.

In previous implementation the first available render surface was
selected. For NVIDIA platform this was the correct one, but for
AMD and Intel GPUs this was incorrect. This PR goes over all the
available render surfaces and selects a compatible one.
For now when no compatible render surface is found it will still select
the first available one. With the expectation that the screen is drawn
incorrectly and users would report a bug so we can investigate.

Covers the macro ARRAY_SIZE() and STRNCPY.
The problem this change is aimed to solve it to provide cross-platform
compiler-independent safe way pf ensuring that the functions are used
correctly.
The type safety was only ensured for GCC and only for C. The C++
language and Clang compiler would not have detected issues of passing
bare pointer to neither of those macros.
Now the STRNCPY() will only accept a bounded array as the destination
argument, on any compiler.
The ARRAY_SIZE as well, but there are a bit more complications to it
in terms of transparency of the change.
In one place the ARRAY_SIZE was used on float3 type. This worked in the
old code because the type implements subscript operator, and the type
consists of 3 floats. One would argue this is somewhat hidden/implicit
behavior, which better be avoided. So an in-lined value of 3 is used now
there.
Another place is the ARRAY_SIZE used to define a bounded array of the
size which matches bounded array which is a member of a struct. While
the ARRAY_SIZE provides proper size in this case, the compiler does not
believe that the value is known at compile time and errors out with a
message that construction of variable-size arrays is not supported.
Solved by converting the field to std::array<> and adding dedicated
utility to get size of std::array at compile time. There might be a
better way of achieving the same result, or maybe the approach is
fine and just need to find a better place for such utility.
Surely, more macro from the BLI_string.h can be covered with the C++
inlined functions, but need to start somewhere.
There are also quite some changes to ensure the C linkage is not
enforced by code which includes the headers.

xdg_surface_ack_configure must run once the events have been handled
which is not the case configure runs from the event handling thread.
In practice this could lead to glitches resizing windows, although some
flickering on startup remains on KDE which would be good to resolve.
Exiting with multiple overlapping windows (a file selector for e.g.)
reliably crashes.
Closing the windows on exit caused the the keyboard enter handler to be
called with a NULL window surface (wl_surface).
While this doesn't look to be documented anywhere, SDL's code-comments
note this happens when windows have just been closed.
GTK also check surfaces for NULL.
The goal is to make it more explicit and centralized operation to
assign and steal buffer data, with proper ownership tracking.
The buffers and ownership flags are wrapped into their dedicated
structures now.
There should be no functional changes currently, it is a preparation
for allowing implicit sharing of the ImBuf buffers. Additionally, in
the future it is possible to more buffer-specific information (such
as color space) next to the buffer data itself. It is also possible
to clean up the allocation flags (IB_rect, ...) to give them more
clear naming and not have stored in the ImBuf->flags as they are only
needed for allocation.
The most dangerous part of this change is the change of byte buffer
data from `int*` to `uint8_t*`. In a lot of cases the byte buffer was
cast to `uchar*`, so those casts are now gone. But some code is
operating on `int*` so now there are casts in there. In practice this
should be fine, since we only support 64bit platforms, so allocations
are aligned. The real things to watch out for here is the fact that
allocation and offsetting from the byte buffer now need an explicit 4
channel multiplier.
Once everything is C++ it will be possible to simplify public
functions even further.

Only make libdecor a hard-requirement for using Wayland in gnome-shell
when X11 is available, as it's possible to disable Xwayland.
This also fixes window-borders not being used in gnome-shell when
WITH_GHOST_X11 is off.
Now it's possible to test Blender under gnome without libdecor by
uninstalling libdecor & running with DISPLAY environment variable
set to an empty string - useful for troubleshooting issues which
could be caused by libdecor.
This PR enabled the swapchain to be used with AMD GPUs.
The issue is that we had to separate the swapchain into
2 functions and therefore the rendering is also not
controlled at the same time.
Semaphores were finished, before being used and the
driver stalled when waiting for those Semaphores.
This doesn't solve the issue that renderdoc can still
crash the graphics driver.

This PR replaces the previous implementation of the swap chain.
The previous implementation was based on a gaming loop where
inside a single function an image is requested, the drawing occurs
and the requested image is presented on screen.
In blender the drawing isn't controlled in a single function and
this approach lead to freezes, missing frames and other
artifacts.
This approach is not be the final approach but a step into a
direction where the acquiring of the next image in the swap chain
is separated from the swapping.

Previous GHOST_ContextVK would create a logical device for each
context. Blender uses multiple contexts at the same time and wasn't able
to share resources between them as the logical device where different.
This patch will create a single logical device and share them between
multiple contexts. This allows sharing memory/shaders between contexts
and make sure that all memory allocations are freed from the device it
was allocated from.
Some allocations in Blender are freed when there isn't a context, this
was failing in the previous implementation. We didn't noticed it before
as we didn't test multiple contexts.
This patch also moves device specific data structures from VKContext to
VKDevice like the descriptor pools, debug layers etc.

In some cases comments at the end of control statements were wrapped
onto new lines which made it read as if they applied to the next line
instead of the (now) previous line.
Relocate comments to the previous line or in some cases the end of the
line (before the brace) to avoid confusion.
Note that in quite a few cases these blocks didn't read well
even before MultiLine was used as comments after the brace caused
wrapping across multiple lines in a way that didn't follow
formatting used everywhere else.
Detecting when to show warnings about GHOST/XKB modifier
mismatches was rather involved, remove the check as it's
unnecessary for Gnome-Shell >= v43.
Older versions of Gnome-Shell will show warnings on window activation
with modifier keys held.
Reading modifiers from XKB caused a complications in getModifierKeys(..)
when called on a window that was activated, before the keyboard enter
handler had run - because the keys held by GHOST had not yet been
updated by XKB. This caused a problem which Gnome-shell which runs
the keyboard-enter handler after window activation.
This change would have fixed the Super key being stuck, see: #107314.
Keep the previous fix since in the unlikely case GHOST & XKB get out of
sync, stuck modifier keys should still be prevented.
This change means the warning for GHOST & XKB getting out of sync
can be enabled for Gnome-shell again, as it was previously suppressed
as it happened frequently on window activation.
Tapping the OS key to switch windows could cause the OS key to stick.
On window deactivation the OS key was considered held, activating the
window later read the XKB modifier state before the keyboard_enter &
keyboard_modifier callbacks had run.
When they ran later, the mis-match between XKB and GHOST was not taken
into account, causing the OS key to stick.
Apparently we always constructed a Vulkan 1.0 Context, although we
are targetting Vulkan 1.2. This also lead to incorrect expectations
when using the Vulkan Memory allocator.

During createOffscreenContext with VK backend enabled wl_surface
was not stored in the context's user data. This resulted in nullptr
dereference later on during disposeContext. Added a line that sets
user data and additionally added nullptr checks in disposeContext.
