New Map, Set and SetVector implementation

All tests are runnings still, but I need to do more testing in the upcoming days.
This implementation uses a different approach for sharing code between
the different structures. I tried different abstractions in the last weeks
and this is the best one I found so far.

Cycles: Patch embree version

Cycles: Remove unused BVH Builder using Embree BVH

LANPR: Fix render status enum value.

LANPR: Bypass thread redraw viewport on complete.

LANPR: Bypass thread for LANPR calculations.

Add right sidebar region for operator properties

This always shows up right now. Hiding it correctly still has to be
done.

Fix lock variable.

Merge remote-tracking branch 'origin/master' into temp-lanpr-staging

Merge branch 'master' into filebrowser_redesign

Integrate the OpenXR SDK better into dependency management

Adds the SDK so that `make deps` works, on all platforms. On Windows,
the SDK headers and libraries are now assumed to be in the usual lib
directory.
Also fixes a mistake in install_deps.sh

Note that none of this is tested as it requires an older Visual Studio
version than I have.

low level memory utilities in blenlib

Merge branch 'master' into functions

Fix particle tetrahedon mesh generation

Merge branch 'master' into greasepencil-object

GPencil: Interpolate pressure in active Smooth

Now the pressure is interpolated in active smooth and not only position as before.

LANPR: Threaded render status flag.

Cleanup: spelling, change breaked to braked

Cleanup: unused warning

Revert "GPencil: Increase number of input samples to 50"

This reverts commit dd370cbf8956d5d1cde0c5e42251c9dbf93d16d8.
