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.

48690d967a GPUContext: Move GPUContext to gpu::Context for more consistency
This makes the GPUContext follow the same naming convention as the rest
of the module.

Also add a static getter for extra bonus style (no need for casts):
- Context::get()
- GLContext::get()

5c2ac8520e GPUQuery: GL Backend isolation
This is part of the Vulkan task T68990.

This introduce a new GLQueryPool for managing queries in an
implementation agnostic manner.

This modify the GPU selection query to use this new object.
This also make use of blender::Vector for better code quality.

No real functionnal change.

bb2aeb4504 GPUVertBuf: Rename GPUVertBuf to VertBuf and add some getters
to avoid more typecasts.

4ea93029c6 GPUIndexBuf: GL backend Isolation
This is part of the Vulkan backend task T68990.

There is no real change, only making some code re-organisation.
This also make the IndexBuf completely abstract from outside the
GPU module.

This just add back the support.
This commit also includes a bit of cleanup.

f3a65a1b4a GPUFrameBuffer: GL backend isolation
This is related to the Vulkan port T68990.

This is a full cleanup of the Framebuffer module and a separation
of OpenGL related functions.

There is some changes with how the default framebuffers are handled.
Now the default framebuffers are individually wrapped inside special
GLFrameBuffers. This make it easier to keep track of the currently bound
framebuffer state and have some specificity for operations on these
framebuffers.

Another change is dropping the optimisation of only configuring the
changed attachements during framebuffers update. This does not give
any benefits and add some complexity to the code. This might be brought
back if it has a performance impact on some systems.

This also adds support for naming framebuffers but it is currently not
used.

c4f122ac8f GPUUniformBuf: GL backend isolation
This is in preparation of vulkan backend. We move all opengl
functionnalities behind an abstract class.

This also cleansup the "dynamic" ubo create and rename it to
`GPU_uniformbuf_from_list()`

Contains, no functional change.

Part of T68990 Vulkan support.

1dd7377596 GPUBackend: Add new GPUBackend object to manage GL object allocations
This just set a global object responsible for allocating new objects
in a thread safe way without needing any GPUContext bound to this
thread.

This also introduce the GLContext which will contain all the GL related
functions for the current context.
