Fix: Wrong fake user icons in outliner orphan mode

The icons for toggling fake users on orphan datablocks in the outliner
were drawn as the quit and x icons instead of the fake user icon. This
changes to the correct icon, and removes the redundant "F" column.

UV Editor: Fix Vertex Overlay color not being color managed

Could be backported to 2.83 LTS

Fix T62917 UV editor: Edge overlay not shown when edge overlay type is Dash

Fix by changing the shader to always compute dash for uv and just change
dash size to something really big for other overlay types.

Subdiv CCG: Add access to first grid index of a face

Is lazily-initialized array owned by the SubdivCCG. Allows to access
index of a first grid of a given face in the flat array of grids.

Currently unused, but is needed for multires bake.

Fix (unreported) broken UI of modifiers for liboverrides.

Broken in recent refactor of modifiers UI code...

Fix random crash in Cycles smoke volume loading

Don't access evaluated mesh data after freeing Blender depsgraph.

Potentially related to T77954.

Subdiv: Cleanup, remove unused code

Functions: add utilities that allow creating some multi-functions with less typing

Functions: Various improvements to the spans and generic data structures

Most of this code is covered by unit tests.

Fix Preferences not saved when changing translation settings

UI: Fix untranslated layout headings

UI/BPY: Make layout headings translatable from BPY

This was an oversight when layout headings were added. There's now the regular
translation context option in the Python API.

Fix constraint alignment check on snap axis to plane

Tools: rename 'Extrude, Dissolve and Intersect' to 'Extrude Manifold'

Transform: Full snapping support for Vert Slide

Now all options for "snap to" affect the Vert Slide mode.

Cycles: enable Embree by default for CPU rendering

For GPU debugging purposes, it is still possible to render with the same BVH2
on the CPU using the Debug panel in the render properties.

Note that building Blender without Embree will now lead to significantly reduced
performance in CPU rendering, and a few of the Cycles regression tests will fail
due to small pixel differences.
