Uses the OpenXR extension XR_FB_PASSTHROUGH_EXTENSION_NAME,
compatible mainly with the Meta Quest family of devices.
Currently, passthrough support over OpenXR is disabled by default
in the Quest Link app, and must be manually enabled in its settings
to use this feature.
The performance of the passthrough render varies with the quality
of the connection between the headset and the PC. For better results,
connecting the headset directly through USB to the PC, or at least
connecting the PC to the local network over ethernet, is recommended.
Thanks a lot to [KISKA](https://kiska.com/)
for their support in the development of this feature.

Multi draw indirect is used by the overlay engine and can lead
to a validation error when multiple instances are drawn.
This PR enabled the feature. We expect that all our devices can handle
this feature.

The currently available `wayland-protocol` libraries in lib-linux_x64
repo do not appear to be advertised 1.36 (or 1.35) versions, since the
tablet protocol is not available among the stable ones.
This reverts commit 2a85eaaf16.

Add support for VK_EXT_dynamic_rendering_unused_attachments. Although
this is required, it needs to be registered optional for now due to
lacking support when using renderdoc.

`VK_EXT_shader_stencil_export` isn't supported by NVIDIA devices.
This extension was recently added to support EEVEE PBR layer selection.
This PR makes this extension optional and selects the work around
when not supported by the physical device.
Fixes#114385

Vulkan backend has recently switched to a render graph approach. Many
code was left so we could develop the render graph beside the previous
implementation. Last week we removed the switch. This PR will remove
most of the unused code. There might be some left and will be removed
when detected.

This makes it more verbose, and a little clearer that devices prior to 8cx Gen3 are not supported in >=v4.0. It makes the error message from #113674 more prominent than just being printed to cout.
Spurred by an email I got from someone trying to run blender on a Surface Pro X, and getting the not very helpful (to old devices) error.

This PR hooks up the vulkan backend with the render graph
for drawing. It can run Blender better than the previous
implementation so we also flipped it to be the default
implementation.
**Some highlights**
- Adds support for framebuffer load/store operations
- Adds support for framebuffer subpass transitions
- Fixes workbench shadows
- Performance is just below OpenGL performance when comparing
fps. But the screen feels more fluent when using complex
scenes.
- Current performance is without doing any optimizations so
will improve in the future.
- EEVEE will not crash but has artifacts and many parts that
require more work.
**Related to**
- #121648
- #118330
**Known Limitation**
- Similar to previous implementation resources can be freed when
still in use crashing Blender. This is typically the case when
playing back an animation or updating a material icon.
**Next steps**
- Remove old implementation
- Get EEVEE to work
- Fix double resource freeing
- Improve performance by identifying hotspots and change them

Vulkan layers should not be controlled from application, but
should be enabled via `vkconfig`. There are configurations
in the layers that are mutual exclusive and hard to maintain from
within an application.
An example is that currently we are not able to use renderdoc efficient,
because there is an validation error triggered from within renderdoc.
This PR removes all vulkan layer configuration from Blender.

When VK_EXT_maintenance4 extension is used at device creation its
extension should also be part of the device extension list.
This wasn't the case and would trigger UB in the validation layers.

In the near future the legacy framebuffer/renderpass/pipeline drawing
will be replaced by dynamic rendering. Dynamic rendering provide a
flexible API to reuse pipelines between framebuffers if they share
the same image formats.
Dynamic rendering is provided by `VK_KHR_dynamic_rendering` extension
and is supported by all platforms we support (Intel since HD4000, NVIDIA
since 700, AMD since GCN2 and llvmpipe).
Functions provided by extensions are loaded in a struct inside
`VKDevice`.

This is because sse2neon.h might be used to emulate SSE intrinsics
on ARM64 architecture, and it uses some preprocessor which is not
available for C language when using MSVC.
The old-style math file math_matrix.c uses this header, so needed
to become C++. Simple rename did not work since there is a new math
utility math_matrix.cc exists. Following some existing convention
the math_matrix.c is renamed to math_matrix_c.cc. Eventually all the
code should switch to use C++ style math, and the C style removed,
so it seems reasonable to not mix old and new style of API in the
same file.
There should be no functional changes.

This reverts commit a63e44a61f.
This lead to build failures on linux because `wl_display_get_protocol_error`
is not defined. The error happened on the buildbot too.
Check & print a message if there is an error creating the window.
In both cases Blender will fail to start, it's just better to exit
quickly with a message instead of hanging.
This change was made previously [0] but reverted as it caused the
title-bar to disappear on Ubuntu (see #121241).
Check if the value is set to GNOME delimited by `:`.
Previously checking the interfaces was used which has the down-side
that any compositor that adds `gtk_shell*` support may hang on startup
because of bugs in Blender/LIBDECOR as happened with WAYFIRE,
see reply to #76428.

Disable use of LIBDECOR on WAYFIRE as it causes Blender to hang
on window creation.
Detect WAYFIRE using the presence of the `zwf_shell_manager_v*`
interface, don't use LIBDECOR if this is found.
This is an alternative fix to [0] which also disabled LIBDECOR
but caused LIBDECOR not to be used in GNOME on some systems.
I'm not keen on this solution, but it seems alternatives are less
reliable. See code-comment for details.

This reverts commit 3a5389d5ab.
It seems XDG_CURRENT_DESKTOP isn't reliably set,
causing no titlebar on GNOME, see #121241.
The WAYFIRE workaround will need to be resolved another way.
Use XDG_CURRENT_DESKTOP to check if GNOME is running.
Previously the existence of a `gtk_shell*` interface was used however
the WAYFIRE compositor provides this interface which made GHOST require
LIBDECOR.
Initializing LIBDECOR was hanging as the initial configuration was
never seen. From a quick check it doesn't seem like a bug in Blender's
LIBDECOR use, the issue may be in either LIBDECOR or WAYFIRE.
Whatever the case, LIBDECOR isn't needed so workaround the bug by
changing how GNOME is detected.
Support detecting if the trackpad direction flag is propertly set
(currently unused).
Needed so Wayland compositors that don't support seat-version 9 or
newer (GNOME-46 & KDE5 for e.g) can have a working trackpad.
Eventually this option will be removed when the functionality is
widely supported.
Accumulate scrolling for mouse wheels that create scroll values below
a single "click".
Regression in [0], caused by bumping the seat API.

When turning on VR mode, if no controllers are available,
a fallback model (a sphere) is rendered in the middle of the VR area.
This change uses the OpenXR API to check if the controllers are
available, sets new properties in `GHOST_XrPose` and `wmXrController`
that store if each controller is active or not, and uses
those properties to render the controllers in the VR view only
when they are active.
NOTE: in `wmXrController`, two state properties have been included,
but only `grip_active` is currently used. `aim_active` has been
included for consistency, but it could be removed.
