This PR enabled device features that are required for EEVEE-Next.
Enabling these features would allow an initial screen drawn by
EEVEE-Next.
Note:
* Changes to EEVEE-Next after this commit, might require other changes
* Not all features are working, but a basic diffuse cube without shadows
is.
* Vulkan views are not correct and leads to incorrect lighting.

The check for control characters didn't account for delete (127).
This wasn't noticeable in most cases as delete is mapped to delete text.
Pressing Shift-Delete would enter 127 control character in the
text-editor, 3D text & Python console. This happened X11 & Wayland,
I didn't check other platforms.
Ghost uses vulkan in its public headers but none of the projects that
depend on ghost had the vulkan headers in its includes nor did
bf_intern_ghost expose this vulkan dependency itself publicly yet.
bf_windowmanager also did not express its dependency on
bf_intern_ghost yet used its headers.
this change fixes both issues.

Shader draw parameter support is needed for Workbench-next. (Almost) All
devices that we support also supports shader draw parameters. This PR
doesn't include a workaround for devices that don't have support.
For end-users this PR will allow workbench-next to render the object on
the correct location. Before this patch they were always drawn on the origin.
The catch is that OpenGL uses gl_InstanceID which always starts counting at 0.
Vulkan has gl_InstanceIndex which holds the correct instance number. By
subtracting the gl_InstanceIndex from gl_BaseInstance will get the correct
gl_InstanceID.
This patch also activates some device extensions to perform in shader printf
statements inside a shader. Documentation for this will be added to the dev
docs how to use them.

Problem caused by [0], resolve by only printing error messages
when none of the GHOST back-ends are able to start.

This is a rewrite of GHOST_ContextVK to align with Metal backend as described
in #111389 - solution 3 with the adaptation that GHOST is still responsible
for presenting the swap chain image and a post callback is still needed in
case the swapchain is recreated.
This PR also includes some smaller improvements in stability.
Technical documentation: https://developer.blender.org/docs/eevee_and_viewport/gpu/vulkan/swap_chain/
* Renderpasses and framebuffers are not owned anymore by GHOST_ContextVK
* VKFramebuffer doesn't contain a swap chain image.
* Swapchain images can only be used as a blit destination or present source.
Not as an attachment.
* GHOST_ContextVK::swapBuffers would call a callback with the image the
GPU module needs to blit the results to.
* Clearing of depth/stencil attachments when no depth write state is set.
* Enable VK_KHR_maintenance4 to relax the stage interface mapping.
* Removes most vulkan validation warnings/errors.
* Detection of frame buffer changes that needs to be applied before
performing a command requiring render pass (draw/clear attachment)
**Benefits**
* Late retrieval of a swap chain image results in better overall performance as
Blender doesn't need to wait until the image is presented on the screen.
* Easier API and clearer state (transitions)
* More control over Image layouts and command buffer states. (Better alignment with
Vulkan API)

Implements the GHOST_GetPixelAtCursor for the X11 backend, allowing
the user to sample any color displayed on the screen.
Noted some limitations in the code-comments.
Ref !111493.
- GHOST_SystemPathsCocoa::getUserSpecialDir
used `strncpy` without ensuring the string was null terminated.
- GHOST_SystemPathsCocoa::getBinaryDir
used `strcpy` without checking the destination buffer size.
The recent change to header copyrights [0] unintentionally changed
"Blender Foundation" to "Blender Authors" for the WIN32 file path
which blender is installed into.
Revert lines changed that aren't related to copyright text.

This adds a new Ghost function, GHOST_GetPixelAtCursor, that allows
picking colors from outside of Blender windows. This only has an
implementation for the Windows platform, but this should allow other
platforms to also do so if possible.

Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
With the introduction of metal and vulkan we use a different
GPU backend selection which broke the dialog box for unsupported
platforms.
Blender asserted and segfaulted before the dialog was being shown
to the user.
This patch solves this by introducing a dummy GPU backend in case no
GPU backend was supported by OpenGL, Metal and Vulkan Backend.
It also adds the showMessageBox to GHOST_SystemCocoa.

Add a High Dynamic Range option in the Color Management > Display panel.
This enables display of extended color ranges above 1.0 for the 3D
viewport, image editor and render previews.
This requires a monitor that can display HDR colors, and a view
transform designed for HDR output. The Standard view transform works,
but Filmic does not as it was designed to bring values into the 0..1
range for SDR displays.
This patch is limited to allowing the display to visualize extended
colors, but does not include future looking work to better integrate HDR
into the full workflow.
It is implemented by rendering to high bit-depth texture formats for
the user interface, and uncapping the color range in color management.

This add the possibility to define different
viewports inside a single framebuffer and
let the vertex shader decide which viewport
to render to.
This only contain the GL and VK implementation.
The Vulkan implementation works but still
has a validation error related to shader features
and extension. The test passes nonetheless.
