`shaderOutputLayer` and `shaderOutputViewportIndex` are optional in
Blender, but when used they should be activated on physical device level.
This wasn't the case and when used the validation layer reported an error.
This PR activates the features when creating the device if the features
are available.

While the fix worked in my tests, the compositor is allowed to ignore
a requested window state change which could have entered an eternal
loop. Avoid this by limiting the while loop to 2x round-trips.
Even though the window was maximized, the non-maximized size was used.
Since the display size was used the window would be slightly larger,
clipping the status bar in GNOME.
As the window state will have been initialized, read the current window
state instead of assuming normal so changes are properly detected.
Also note that the cause of #107314 has been fixed up-stream.
When the output wasn't fractionally scaled but the compositor supports
fractional scaling, new windows were smaller than requested.
Caused by [0] which was incorrectly calculating the non-fractional scale
used by LIBDECOR (which isn't accessible via it's API).
Resolve by only using fractional scaling logic when outputs
have a fractional component.

Tested with IBUS on GNOME 45.
Added a capabilities flag to GHOST since support for IME works on
Wayland but not on X11, so runtime detection is needed.
The USE_LIBDECOR_FRACTIONAL_SCALE_HACK worked on my system but made
window size issues worse in older versions of GNOME, see: #109194.
Replace the hack with logic to set the window size using frational
scaling information from the output.
When fractional scaling is used, window sizes from LIBDECOR are still
divided by the window-decorations internal buffer scale which doesn't
match the GHOST window (always 1 in the case of fractional scale).
Also resolve glitches caused by recalculating the window size when
no size change was intended. In this case reuse LIBDECOR's internal
size so there are never any changes (caused by rounding for e.g.).
When the window manager set the window size, there were no checks
the size is a multiple of the buffer scale (a requirement for Wayland).
This meant setting the window size could exit Blender without warning
if an invalid window size was set.
When fractional scaling was used with libdecor the window decorations
would not match the window size on startup, drawing small and on top
of Blender's window.
While there are still glitches with fractional-scaling & libdecor
(which doesn't support fractional scaling),
see #109194 this at least resolves one of the worst issues.
When a new window is created the final buffer scale isn't known
so setting the buffer scale assuming the final state was just a guess
and only had the minor advantage of preventing rounding the window size
on startup.
Removing this to resolve a bug with LIBDECOR & fractional scaling
relating to #109194 (will commit separately).
When running Blender inside renderdoc an extension can be used to print
from any shader stage to the console. This is useful during developing,
but not so during running/triaging. For now we remove the extension to
not confuse by incorrect error messages.

This PR adds workarounds for platforms that don't support `shaderOutputLayer`
or `shaderOutputViewportIndex`. Some NVIDIA laptop GPUs and ARM GPUs don't
have those device features.
The workaround uses the same approach as OpenGL. A geometry shader is injected
to emulate the feature.
For testing the workarounds they have also been connected to the
`--debug-gpu-force-workarounds` command line argument.

Windows mouse warping bounds margin needs to be different when not
GHOST_kGrabHide, or else the visible wrapping occurs within the
area at an odd location. Making it 2, like it used to be.
The issue was caused by the custom code which was ensuring that closing
About window does not leave application without any key
windows.
Turns out that the windowWillClose is executed when menu is closed,
forcing the custom code to ensure a key window.
The solution is to only perform manual re-ordering if the closing window
was a key window. This both keeps old behavior of ensuring there is a
key window after closing About, and solves the ordering issues when a
window is created or activated via menus.
