bf3f4da947 GPU: Fix wrong state before python callbacks
This was caused by a missing state apply.

We force the GPUState to be set after the callbacks to avoid
desync between our state tracker and the real gl state.

This fixes some issues but a better general fix for all BGL would
be better.

This fix T80297 2.91 texture alpha is not transparent

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.

9d5977f5e1 GL: Add fallback debug layer
This is to improve debugging on older hardware that may not support
4.3 debug capabilities (like Macs).

This avoids sprinkling glGetErrors manually. This might still be needed
to find the root cause since not all functions are covered.

This overrides the functions pointers that GLEW have already init.

This is only enabled if using --debug-gpu option and the debug extension
are not available.

This also cleanup the usage of GLContext::debug_layer_support and use
wrapper to set object labels.

28ea459a61 GPUState: Encapsulate glPixelStorei inside the GLStateManager
Part of the Vulkan task T68990

Isolate the last remaining gl functions.

7d4adbdfab GLTexture: Add validation for empty slots before drawing
This is to have better error detection in debug builds.
This is not a replacement for a full check like in renderdoc but it
might catch some issues early on.

c766d9b9dc GPUTexture: GL Backend Isolation
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).

8527d84d35 GPUState: Move Scissor and Viewport state to framebuffer
This way it is way clearer what each viewport state is. There is
no more save and reset. The scissor test is also saved per
framebuffer.

The only rule to remember is that the viewport state (size and
origin) is reset for both the viewport and scissor when a texture
is attached or detached from an attachment slot.

97f75ca87f GPUState: Move state limits getter to the area they belong
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 avoid confusion about what is a class and what is an opaque
pointer.

f30df15edc GPUState: Make use of GPUStateStack class
This isolate most GL calls to the GL backend. Still a few remains.

2ae1c895a2 GPUState: Add GL backend and state tracking but do not use it
This is just the backend work. It is not plugged in yet because it
needs more external cleanup/refactor.
