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

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

Custom Menus : fix build error due to library update

Cleanup: GPUTexture: Clean framebuffer attachment

Refactoring changes and cleanup

- Updated shader tests for `workbench_shader_volume_get()`
- Naming updates in the enums for interpolation methods in fluid and volume display.
