Fix T89870: Vertex groups lost when opening 3.0 files in 2.93

The original refactor for vertex groups (3b6ee8cee708)
forgot to bump the minimum file requirement.

I'm also bumping the subversion to 12 so everyone can switch to a
working subversion number.

Fix: crash when creating new node links

This was a regression in rBc27ef1e9e8e663e02173e518c1e669e9845b3d1f.

Cleanup: LayerCollection resync code.

Mainly naming (also droping the `layer_collection` in favor of just
`layer` for internal code, this is clear enough and much shorter). Add
proper parent/child identifiers, `r_` prefix for parameters also used as
return values, etc.

Also made some parameters const.

Keymap: use Shift-Tab to toggle snap in the sequencer

Match the same shortcut for the 3D view & UV editor.

Cleanup: improve comments, remove debug printf

Cleanup: LayerCollection resync: Proper `r_` prefix for return function parameter.

Add support for RISC-V architecture

* On RISC-V GCC 10.3 does not define __GCC_HAVE_SYNC_COMPARE_AND_SWAP_n.
* Avoid a build error
"Please add support for your platform in build_config.h"

Fix: Subtitles: Order of channels in the .blend file will be kept in the .rst file.

If text strips have the same start frame but are stacked on top of each
other in different channels the order in which they are written in the
.rst file was random before.

Library loading: Fix access of out-of-scope memory in py context manager

The `__enter__` function of the `bpy.data.libraries.load` context manager
was storing a pointer to a stack-allocated variable, which was subsequently
used in the `__exit__` function, causing a crash. This is now fixed.

Thanks @Severin for the patch.

Fix T88188: Allow keyframing vertex mass in cloth sim

Update vertex weights between simulation steps if they have changed.
This allows for animated vertex weights in the cloth sim.

Assets: Add an active asset library per workspace, for the UI to use

This per-workspace active asset library will be used by the asset views
later. Note that Asset Browsers have their own active asset library,
overriding the one from the workspace.

As part of this the `FileSelectAssetLibraryUID` type gets replaced by
`AssetLibraryReference` which is on the asset level now, not the
File/Asset Browser level. But some more work is needed to complete that,
which is better done in a separate commit.
This also moves the asset library from/to enum-value logic from RNA to
the editor asset level, which will later be used by the asset view.

Assets: Expose active asset library in context

For the Asset Browser, this returns the active asset library of the
Asset Browser, otherwise it returns the one active in the workspace.

This gives simple access to the active asset library from UI code and
Python scripts. For example the upcoming Pose Library add-on uses this,
as well as the upcoming asset view template.

Bezier Spline: Add a more generalized insertion utility

This logic is from the curve sundivide node, used to add points with
proper handles in between two existing points. However, the same logic
is used for trimming of Bezier splines, and possibly interactive point
insertion in the future, so it's helpful as a general utility.

The logic is converted to depend on a bezier spline instead of being
static. A temporary segment spline can be used for the latter use case.

CMake: Have CMake Control the C++ version.

We were manually setting the compiler flags
for C++17 support for this previously. CMake
can do this for us in a uniform way without
having to worry about compiler specifics.

Setting these flags manually somehow brought
out some unwanted behaviour (CMake switching
back to C++14) in the nightly CMake builds.

Unsure if that's a CMake bug or planned
new behaviour for future version, but best
to play it safe.

These flags are supported since CMake 3.1
so should not break anything.

Useful when TLS requires it's own allocated structures.

CMake: update config for checking utility

Cleanup: ensure one newline at end of file, strip trailing space
