Cleanup: remove duplicate doc-strings

Internal struct ObTfmBack had out of sync doc-strings
for members duplicated from Object.

Remove the doc-strings as there is this is just temporary storage.

Cleanup: spelling in comments

Cleanup: compiler warnings

Cleanup: use doxygen for BLF glyph

- Use doxy formatted functions.
- Use doxy sections.

Fix snap cursor not active even if gizmo is available

Error introduced in rB69d6222481b4 and partially fixed in rB24310441ddc8.

When gizmo was turned on but the scene has more than one 3D viewport, one of them the snap cursor did not appear.

Cleanup: Clang tidy

Cleanup: Convert mesh.c to C++

This commit renames mesh.c to mesh.cc and makes
it compile in C++. Can be useful in the future to be able
to use C++ functionality in existing and new functions.

Cleanup: remove window_manager & editor includes from BLF

Remove the need to include the window manager & editor functions
in low level font rendering code.

- The default font size is now set when changed in the preferences.
- Flushing cache is set as a callback.

Fix: Property editor icon jittering in some cases

In the tools tab, the tool icon would be offset when it intersected
the bottom of the editor. With some screen resolutions, the icons on
the left side of the editor would also move when intersecting the
bottom of the editor. This happened because of the truncation in
the implicit conversion from float to int. Instead, use explicit
conversion functions.

Cycles: perform CPU film reading in the kernel, to use AVX2 half conversion

Adds a bunch of CPU kernel function to process on row of pixels, and use those
instead of calling unoptimized implementations.

Fixes T92598

Fix T91733, T92486: Cycles wrong shadow catcher with volumes

Changes:
* After hitting a shadow catcher, re-initialize the volume stack taking
into account shadow catcher ray visibility. This ensures that volume objects
are included in the stack only if they are shadow catchers.
* If there is a volume to be shaded in front of the shadow catcher, the split
is now performed in the shade_volume kernel after volume shading is done.
* Previously the background pass behind a shadow catcher was done as part of
the regular path, now it is done as part of the shadow catcher path.

For a shadow catcher path with volumes and visible background, operations are
done in this order now:

* intersect_closest
* shade_volume
* shadow catcher split
* intersect_volume_stack
* shade_background
* shade_surface

The world volume is currently assumed to be CG, that is it does not exist in
the footage. We may consider adding an option to control this, or change the
default. With a volume object this control is already possible.

This includes refactoring to centralize the logic for next kernel scheduling
in intersect_closest.h.
