UI: Move render display type to Preferences

Moves the render display type (to choose between rendering in a new
window, in a fullscreen area, in an Image Editor, etc) from the scene to
the preferences.

Refactor temp-space opening for optional fullscreen mode

Will be put to use in followup commits.

Cleanup: minor changes to paint undo

Use a shared tile freeing function.

Fix segfault when polling OBJECT_OT_voxel_remesh without active object

The active object can be `NULL`, which causes a segfault in
`BKE_object_is_in_editmode(NULL)` (and if that were made NULL-safe, the
segfault would happen further down in `object_remesh_poll()`).

LANPR: engine added for other panels.

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

Cleanup: includes for readfile.c

Fix T69989: Correct Mapping node min/max versioning.

The old min/max options specified the target min/max values, they didn't
act as min/max operators. So the versioning code should be adjusted
accordingly.

Merge branch 'blender-v2.80-develop' into blender-v2.80-master

GPU: Comment incorrect asserts

These asserts are too simple and triggers false positive.

Fix T69809, T69810: sculpt gone or crashing after render

Make a distinction between flush sculpt changes for rendering, and forcing
sculpt data structures to be rebuilt after mesh changes. Also don't use PBVH
for renders.

Cleanup: Don't pass unused lens value

Cleanup: Comment style

CMake: Slight adjustment to warning message

Fix Linux linker config name for the OpenXR-SDK

Fix mistakes in openxr build options

I remember merge conflicts here.

GPU: Fix broken assert

Merge branch 'master' into greasepencil-object

Cycles: Improve convert time from Embree

Fix paint cursor crash

The new paint cursor (introduced in rBe0c792135adf) could crash for 2d
painting without an active object.

Note there are still drawing asserts (because we are mixing 2d and 3d
drawing in 'paint_draw_cursor'), but these will be handled in a seperate
commit.
