This reverts commit a21f5ec56245f7f1fbede4aa3c140a582c3a6a1b.

Shading: Extend Vector Math Node with Sin, Cos, Tan and Wrap functions

This adds some extra functions recently added to the float Maths Node.
Not all functions have been ported over in this patch.

Also:
+ Tidy up menu
+ Change node color to match other vector nodes, this helps distinguish vector and float nodes in the tree
+ Move shared OSL functions to new header node_math.h

Fix property warning due to recent commit

```Warning: property 'mode' not found in keymap item 'TRANSFORM_OT_bbone_resize'```

build_environment: Upgraded Embree to 3.8.0

The latest versions of Embree allow similar motion interpolation
as Cycles' own BVH.

Fix failing assert & uninitialized paint settings in empty scene

Steps to reproduce were:
* Add new (empty) scene
* Add some mesh object
* Change to texture paint mode

While it can be argued that we should already init the settings when
creating a new scene (so that the texture tab can show up),
BKE_paint_init() should always ensure paint settings are initialized
either way.

Fix sporadic CUDA launch failures with Cycles viewport denoising

Sometimes the viewport buffer size is zero for a frame, which caused the denoising task to also try to
launch CUDA kernels with a launch size of zero, which in turn failed with a CUDA error. This patch
prevents launches from occuring in this case, similar to how it is handled in `copy_to_display_buffer`.

Cleanup: Fix compiler warning

Cleanup: Rename ED_region_tag_redraw_overlay() to ED_region_tag_redraw_cursor()

Old name was a bit confusing/misleading, esp. since previous commit.

UI: Allow gizmo-only redraw tagging

NOTE: This change shouldn't have any visible effect. It's just the
first (easiest) step towards decoupling gizmo redraws from viewport
redraws.

We currently redraw the entire region whenever a gizmo needs redrawing,
which would be nice to avoid in the future, see T73198. The first step
towards this would be having a separate tag for them, which is what
this patch implements.
The term "editor-overlays" was chosen because for the forseeable future,
we'll also have to redraw non-gizmo overlays in-between drawing 3D and
2D gizmos. Namely annotations.

Cleanup: Alembic, renamed and moved convert_matrix function

The `convert_matrix()` function just converts between the Alembic and
Blender matrix data types, and doesn't do any coordinate system conversion.
To clarify this, the function has now been renamed to
`convert_matrix_datatype()`.

I also moved the implementations next to each other in the source file,
so that it's visible that there are actually two of them.

Cleanup: Alembic, removed unused export settings

Alembic: refactor import and export of transformations

The Alembic importer now works with local coordinates. Previously, the
importer converted transformations from Alembic to world coordinates
before processing them further; this processing often included
re-converting to local coordinates. This change made it possible to
remove some code that assumed that a child transform was only read after
its parent transform.

Blender's Alembic code follows the Maya convention, where in the zero
orientation the camera looks forward instead of down. This extra
rotation is now handled more consistently, and now also properly handles
children of cameras. This fixes T73269.

Unit tests were added to at least ensure that the importer and exporter
are compatible with each other, and that static and animated camera
transforms are handled in the same way.

Cleanup: Alembic, rename unit test

This rename is to prepare for a future addition to the unit test file.
Currently it's named "import" and I will add an export test as well. The
rename is a separate commit to easily see the difference between the
rename and the addition of another test.

No functional changes.

Fix T73763: Laggy with nodes Editor + International Fonts

Two main reasons for the lag:
- Allocation of memory with transfer to GPU.
- BLF_cache_clear();

The memory allocation seems to be unnecessary, so I removed it.
