87055dc71b GPU: Compute Pipeline.
With the compute pipeline calculation can be offloaded to the GPU.
This patch only adds the framework for compute. So no changes for users at
this moment.

NOTE: As this is an OpenGL4.3 feature it must always have a fallback.

Use `GPU_compute_shader_support` to check if compute pipeline can be used.
Check `gpu_shader_compute*` test cases for usage.

This patch also adds support for shader storage buffer objects and device only
vertex/index buffers.

An alternative that had been discussed was adding this to the `GPUBatch`, this
was eventually not chosen as it would lead to more code when used as part of a
shading group. The idea is that we add an `eDRWCommandType` in the near
future.

3f4f109646 Python GPU: New 'capabilities' module
This module exposes the capabilities defined in the GPU module in C.

This will be useful for porting existing code in `bgl` to `gpu`.

549d9f8727 Fix T81206: Do not limit gl texture size in image editor
This patch will show textures in the image editor with the maximum
available resolution determined by the GPU Hardware/Driver.
Currently the size is limited by the user preference texture size limit.

An image user can set the `IMA_SHOW_MAX_RESOLUTION` flag to request
gpu textures in the max supported resolution. When this flag isn't
set the gpu texture is limited by the user preference setting.

When the gl resolution limit is disabled the GPU texture is always
created for the max supported resolution.

a3fcbb54f4 GPU: Add HQ normals workaround.
This change makes it possible for platforms to only support high quality
normal rendering. This is part of {T82856} where current AMD drivers
running on the polaris architecture does not support the low quality
setting due to a driver bug.

In a next commit the work around will be enabled.

136bdb561b GPU: Add Image Load Store extension support
This wraps the functionality used to speedup EEVEE volumetrics.

This touches the rendering code of EEVEE as it should fix a mis-usage of
the GL barrier. The barrier changed type and location, removing an
unused barrier.

6b436b80a4 GPU: Rename gpu_extensions to gpu_capabilities
This makes more sense as this module has more to it than just
GL extensions.
