Cleanup: GPUTexture: Remove use of GPU_texture_create_nD

Use creation + update function instead.

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.

OCIO: Use GPUTexture instead of OpenGL calls and remove gl dependency

Simple cleanup. Part of the Vulkan Port T68990.

GPUTexture: Implement back 3D texture resize

But this time implement it outside the texture module.
This makes more sense as only the volume textures need this feature.

BLI: Math: Add equals_v3v3_int

Cleanup: GPUTexture: Clean framebuffer attachment

Cleanup: GPUFrameBuffer: Use Texture class instead of gl calls

GLTexture: Add back texture proxy check

Cleanup the feature itself:
- Check 3D textures size against the correct limit.
- Add check for compressed textures.

GPUTexture: Add support for samplers

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

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).

GPUFramebuffer: Encapsulate single attachement clear

This is in preparation of using it to clear single texture.

Also includes minor cleanups about not using tex target in
assert and adding enum operators.

Cleanup: EEVEE: Use correct array size and use equals_v2v2_int

GPUTexture: Add skeleton of the new GLTexture class

GPUTexture: Remove bind to edit calls

This is going to be unecessary after the GPU opengl texture backend refactor.

For now add a save/restore mechanism to leave the state untouched.

Also remove some calls where the caller would bind to particular binding
point and set the shader uniform.

GLDebug: Trim NVidia debug output

These buffer detailed infos are not needed unless going deep into
perf. profiling, in which case you can still disable this compile option.

This makes user report log much more readable.

GLTexture: Fix texture creation when using direct state access

There was 2 errors:
- A texture object must have been bound to target_ before use with DSA funcs
- We need to use glTextureSubImage for DSA updating

Merge branch 'master' into greasepencil-object

Merge branch 'master' into greasepencil-edit-curve

GLTexture: Add Feedback loop check

The check is better than before as we take into
consideration the attached mip level.

Cleanup: GPUFramebuffer: Remove unused variable
