93bf17d952 GPU: Add support for stencil buffer texturing mode.
This adds the possibility to read the stencil buffer inside shaders.
This is only available on GL 4.3 so use it accordingly.

1d49293b80 DRW: Move buffer & temp textures & framebuffer management to DrawManager
This is a necessary step for EEVEE's new arch. This moves more data
to the draw manager. This makes it easier to have the render or draw
engines manage their own data.

This makes more sense and cleans-up what the GPUViewport holds

Also rewrites the Texture pool manager to be in C++.

This also move the DefaultFramebuffer/TextureList and the engine related
data to a new `DRWViewData` struct. This struct manages the per view
(as in stereo view) engine data.

There is a bit of cleanup in the way the draw manager is setup.
We now use a temporary DRWData instead of creating a dummy viewport.

83e91485d0 GPU: Fix NOT ~ operator for eGPUSamplerState
The real maximum was `GPU_SAMPLER_ICON`, not `GPU_SAMPLER_REPEAT`, my
bad. {rBa31a87f8943aa40}

Move `GPU_SAMPLER_MAX` out of the enum since it's used as an `int`
at many places.
Also, the macro `ENUM_OPERATORS` needs a maximum, and this enumerator
cannot be used as the argument of that macro. It creates wrong values
in the `~` NOT operator.

Thanks @deadpin for catching this.

a31a87f894 T81340: UBSan: load of value .. not valid for GPU enum type
The underlying type of the enum cannot be fixed here due to its usage
in C code.

All the values possible in the width of the underlying type are not
valid for an enum.
Only 0 to (2*max - 1) if all enumerators are unsigned.
So the macro asks for the biggest value among the //listed// ones.
If any enumerator C is set to say `A|B`, then C would be the maximum.
(2*max-1) is used as the mask.

The warnings (for each enum modified in this commit):
GPU_vertex_buffer.h:43:1: runtime error: load of value 4294967291
which is not a valid value for type 'GPUVertBufStatus'

This is a massive cleanup needed for vulkan support T68990. It provides:

- More meaningful enums with conversion functions.
- Less hacky supports of arrays and cubemaps (all considered layered).
- More inline with the stateless design of vulkan and modern GL.
- Methods Fallbacks are using framebuffer functions that are wrapped
  instead of implementing inside the texture module.

What is not in there:
- API change.
- Samplers support (breaks a few effects).

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.

This should aleviate all issue we have with texture state change recompiling
the shaders at drawtime.

All binds are now treated like persistent binds and will stick until a new
shading group bind a different shader. The only difference is that you can
still change it with a new subgroup or same shader shgroup.

Since unbinding can be heavy we only do it when using `--debug-gpu`.
