Depsgraph: Inform when update or tag happens during evaluation

It is not allowed to do tagging or updates while dependency graph is
in the middle of evaluation.

This is something what is simple to violate from python code. This
change adds some sanity checks.

The request to update view layer or dependency graph will raise an
exception in Python now, so it's easy for scripters to notice.

Tagging for update will do silent return unless running with debug
command line argument. This is because it's a bit tricky to know
which exact dependency graph corresponds to a context from which
an update tag was triggered.

Depsgraph: Cleanup, promote is_evaluating query

This way it might be used for sanity checks in RNA API as well.

Depsgraph: Don't use push-from-thread when scheduling graph

This isn't guaranteed that graph is scheduled from main thread,
so it is actually a miracle how it all worked.

Fix T70191: Text button in popup doesn't work

F2 rename didn't work with mouse input.

Cleanup: remove unused variable

Fix T70715: sculpt brush jitter after recent TBB changes

Fix error in the splitting constructor, and some refactoring.

Fix T64901: Nesting collection instances could clutter object display

Cleanup: Fix wrong assert introduced by rBd98ae27f02c7

GPencil: Change Paint cursor to DOT

After doing some test, the cross cursor is too intrusive when you are drawing in grease pencil, so we decided to change by Dot cursor.

Sculpt: use TBB instead of BLI_task for multithreading

This solves performance issues on some computers where there is significant
threading overhead. Rather than doing the complicated work of optimizing our
own task scheduler, use TBB which appears to work well. The downside is that
we have another thread pool, but it is already there when using OpenVDB voxel
remesh.

For future releases we can switch to using TBB to replace our task scheduler
implementation entirely, and use the same thread pool for BLI_task, Cycles,
Mantaflow, etc.

Build: add WITH_TBB option, in preparation of sculpt using it

It should no longer be tied to OpenVDB and OpenImageDenoise then.

File Browser: add back Delete, which now moves files to the trash

In Blender 2.7 delete would permanently delete files, now this function is back
but using more standard behavior.

This patch includes code contributed by Kris (Metricity).

Node Shader wrapper: add access to the Emission color of Principled BSDF node.

This did not exist when that wrapper was created, but is supported by
many formats, so worth supporting it now. See also T70666.
