Swapchain handling of minimized windows wasn't correct. On some
platforms it still tried to create images with no surface.
This PR will discard swapchains of minimized windows, but still being
able to flush the render graph and free resources.

Vulkan 1.0 render passes have been replaced by dynamic rendering in 1.2.
Blender Vulkan backend was implemented with dynamic rendering in mind.
All our supported platforms support dynamic rendering. Render pass support
was added to try to work around an issue with legacy drivers. However these
drivers also fail with render passes.
Using render passes had several limitations (blending and some workbench
features were not supported). As no GPU uses it and it is quite some code
to support it is better to remove it.

On some drivers, the GLSL compiler doesn't reflect the omitted
`local_size_*` of a compute shader inside `gl_WorkGroupSize`.
This lead to the 2D size computation of 1D workgroups to become
0 which was bypassing the parallel reduction algorithms.
Ensuring `local_size_*` are always set fixes the issue.
For clarity, also fix the 1D shaders to not use `gl_WorkGroupSize.y`.
This also fix a copy paste error in the Metal backend.
This issue affected AMD drivers on Windows.

Candidate for backporting to 4.5 LTS.

Resetting and recycling of immediate drawing buffers was never done and
would leak memory as the buffers were only destroyed when Blender
exited.
This is solved by not recycling or resetting the buffers and rely on the
discard pools. Additional cleanup of removing unused code-paths is also
part of this change so it can be backported to 4.5.

This assert was to notify developers that they are using a framebuffer
configuration that isn't supported when using render passes. Render
passes should not be used and will be removed later in 5.0. Removing the
assert will already help during triaging.

On the Vulkan side, ensure that unbound textures don't result in
accessing uninitialized or out of bounds memory.
On the Draw side, ensure all Hair and Curves attributes have, at least,
a dummy attribute bound.

The numeric levels have no obvious meaning. This removes the distinction
between severity and levels, instead there is a single list of named levels
with defined meaning.
Debug means information that's mainly useful for developers, and trace is for
very verbose code execution tracing.

This PR moves Wayland/HDR support out of experimental.
This allows more people to test and provide feedback. We
can always decide later to disable it for the release, but so
far we only got positive feedback.

Windows/Intel GPU crashes when descriptor buffer cannot be allocated
anymore. This PR enables a workaround by not using descriptor buffers.
In future we should investigate how to improve the GC of descriptor
buffers and review the limits.

In case Blender was able to allocate a vertex buffer for huge geometry,
but isn't able to allocate its staging buffer it would crash. In this
case errors will be reported in the console.
This PR fixes this by clearing the data in stead of uploading.

This change enables HDR support for wayland as an experimental feature.
It supports both non-linear extended sRGB and un-clamped sRGB.
Windows isn't supported as the HDR settings are not accessible via an
API and would require similar settings that games use to configure the
monitor. Adding those sliders isn't what we would like to add.
Vulkan (working group) is working on new extensions that might change
the shortcomings. It isn't clear yet what the extension will do and what
the impact is for applications that want to use it. When the extension
is out we should review at the situation again.

GPU_DATA_UINT_24_8 isn't used anymore. We cannot phase out the data type
as it can still be used by add-ons. This PR will deprecate
`GPU_DATA_UINT_24_8`. When used in an add-on a deprecation message will
be shown.

Metal and AMD/Intel/Vulkan don't support depth24 texture formats
natively. The backends implemented fallback to use depth32f in
stead.
Recently we removed all usages of depth24 to use depth32 and the
next step is to remove the depth24 format and the workarounds in
the backend.
Note: The removal of `GPU_DATA_UINT_24_8` isn't part of this PR.

We detected that the gpu/draw tests could lead to
crashes after the tests where finished. It was
identified that the crash happened as the submission
runner wasn't exited, uses a mutex, that is being
destroyed by the main thread.
Solution is to wait until the submission runner has
finished, before destroying resources.
