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.
This is in preparation of the Framebuffer GL backend.
This is a just changing types and moving some code.
No logic is changed... almost... it just removes the context attach.
i.e: `gpu_context_add/remove_framebuffer()`
This is not needed for now and was even disabled in release.
This is part of T68990.
The CPP Shader class does not initialize the interface attribute.
What will crash when deleting the shader.

In recent refactoring {a9f2ebb21508} an issue was introduced that the
opengl rasterizer would be disabled when only writing to a stencil
buffer.
This fix adds stencil writing to the write mask and set it. This makes
the write map not evaluate to GPU_WRITE_NONE and the rasterizer will be
enabled in `GLStateManager::set_write_mask`.

This fix a GL_INVALID_VALUE error on startup due to 0.0f max line width.
Also moves the max anisotropy filter to the sampler creation.
This reduces code fragmentation.
This should not cause any problem since the depth test is required
in order to draw to the depth buffer and this is not altered by
this change.
To be on the safe side, we still restor the mask after altering it.
This is quite embarassing... it was returning the base instance instead of
the correct vao. No wonder that it was causing crash and at most drawing
issues.
This replace `GPU_clear()` by `GPU_clear_color()` and `GPU_clear_depth()`.
Since we always set the clear value before clearing, it is unecessary
to track the clear color state.
Moreover, it makes it clearer what we clear the framebuffer to.
This changes the state of occlusion queries quite a bit. Now scissors is
explicitely disabled and we enabled color write.
I still don't understand why we now need this. This patch is just trial and
error on an affected setup. Note that on the same computer, renderdoc
was not able to capture the regression (the regression did not manifest
during capture).

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.
This follows the GPU module naming of other buffers.
We pass name to distinguish each GPUUniformBuf in debug mode.
Also remove DRW_uniform_buffer interface.
