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

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

GLTexture: Add direct state access support

GLState: Add texture multibind and remove redundant binds

Math Utils: Add bitscan 64bit version

GPUTexture: OCIO: Workaround new missing bind error checking

We cannot change the texture bind point since the interface count
4/5 textures to bind. Changing the uniform to avoid one bind
make the system thinks one texture is missing.

Avoid this by creating a dummy texture and binding it to the empty
slot.

GPUDebug: Only enable resource checking in debug mode

Cleanup: GPUTexture: Move debug messages outside of creation function

GPUTexture: Change texture creation API

This is to modernize the API:
- Add meaningful name to all textures (except DRW textures).
- Remove unused err_out argument: only used for offscreen python.
- Add mipmap count to creation functions for future changes.
- Clarify the data usage in creation functions.

This is a cleanup commit, there is no functional change.

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.
