Merge branch 'blender-v2.90-release'

UI: disable add-object tool for 2.90 release

This needs improvements which need user testing before this can
be considered finished, even on a basic level.

Cleanup: rename Curve.len_wchar to len_char32

The name was misleading as the length is for char32_t, not wchar_t.

Cleanup: unused argument

Simulation: add todo comment

Nodes: add missing update tags in the case of simulation node trees

Depsgraph: build ids referenced by sockets

Simulation: move responsibility of updating persistent data handles

This solver should not be responsible for updating the handles.

Simulation: fix memory leak

Simulation: improve depsgraph integration

A simulation data block has an embedded node tree, which requires
special handling in a couple of places. Some of those places were
missing beforehand.

This also adds a relation to make sure that the simulation is evaluated
after animations on the embedded node tree are evaluated.

Fix T79144: Snapping bypassing the viewport backface culling

Silently activate the backface culling when the viewport is using.

Cleanup: Fix strict compiler warning

Merge branch 'blender-v2.90-release'

Fix T79160: Bevel modifier set to vertices by default

Need to properly initialize the affect_type field.

master is now 2.91.0 alpha.

Merge branch 'blender-v2.90-release'

Release branch is now in beta.

UI: Use property split for simulation modifier

Ensure submodules are at their correct commits.

Object: add-object option to place on the surface normal

Optionally use the surface normal under the mouse cursor.
