Cleanup: Remove deprecated comment.

Cleanup: Always keep unlock at same level as lock.

This was fine in those cases with current code, but that kind of
assumption is always risky, and an open door to hard-to-track bugs when
code changes in the future...

GPU: Refactor gpu_texture_image to not use GL calls

This is also a bit of code cleanup, reorganisation.

Tried to be DRYed but avoid too much code change to (hopefully) minimize
breakage.

- GPU: remove TEXTARGET_CUBE_MAP, this is no longer used in the codebase.
- GPUTexture: Move compressed texture upload to gpu_texture.cc
- GPUTexture: Add per texture Anisotropic filtering switch

GPU: Move gpu_shader.c to C++

We split builtin shader support to its own file to avoid
converting code (lack of designated initializer in C++)
and to reduce file size.

GPU: Move gpu_state.c to C++

GPU: Move gpu_texture.c to C++

# Conflicts:
# source/blender/gpu/GPU_texture.h

GPU: Move gpu_uniformbuffer.c to C++

This also rewrite and simplify the module a bit.

GPU: Move gpu_vertex_buffer.c to C++

GPU: Move gpu_vertex_format.c to C++

Merge branch 'blender-v2.90-release'

Fix T78826: Move constraint is not fully disabled

Caused by rB45f17e10ec50

Particles: rename Size attribute to Radius

Doing this change for consistency with the point cloud attributes.

Workbench/Eeevee: Minor refactor in smoke draw function

More concise this way.

GPencil: Consider extrude point as last

Before, when extrude a point, the extruded point is considered as the first point of the stroke, but this was not logic.

Now, the extrude point is considered as last.

Related to T79313

Particles: add Size attribute

Fix T79355: switch to texture paint workspace changes image in other workspaces

Only automatically change image in editor to follow texture paint editors and
workspaces that are visible.

Cleanup: rename uiBut.dt, uiBlock.dt to 'emboss'

Use 'emboss' instead of 'draw_type' as enum, layout & functions use
the term emboss.

This issue was noted by @Poulpator in D8414, as `dt` is also an
abbreviation for delta-time.

Cleanup: quiet possible comma misuse warning in feestyle PyAPI

Clanup: unused return

Cleanup: correct assert in GPU_offscreen_read_pixels
