UI/Assets: Initial Asset View UI template

The asset view UI template is a mini-version of the Asset Browser that
can be placed in regular layouts, regions or popups. At this point it's
made specifically for placement in vertical layouts, it can be made more
flexible in the future.
Generally the way this is implemented will likely change a lot still as
the asset system evolves.

The Pose Library add-on will use the asset view to display pose
libraries in the 3D View sidebar.

Notes:
* Important limitation: Due to the early & WIP implementation of the
asset list, all asset views showing the same library will show the
same assets. That is despite the ID type filter option the template
provides. The first asset view created will determine what's visible.
Of course this should be made to work eventually.
* The template supports passing an activate and a drag operator name.
The former is called when an asset is clicked on (e.g. to apply the
asset) the latter when dragging (e.g. to .blend a pose asset). If no
drag operator is set, regular asset drag & drop will be executed.
* The template returns the properties for both operators (see example
below).
* The argument list for using the template is quite long, but we can't
avoid that currently. The UI list design requires that we pass a
number of RNA or custom properties to work with, that for the Pose
Libraries should be registered at the Pose Library add-on level, not
in core Blender.
* Idea is that Python scripts or add-ons that want to use the asset view
can register custom properties, to hold data like the list of assets,
and the active asset index. Maybe that will change in future and we
can manage these internally.

As an example, the pose library add-on uses it like this:
```
activate_op_props, drag_op_props = layout.template_asset_view(
"pose_assets",
workspace,
"active_asset_library",
wm,
"pose_assets",
workspace,
"active_pose_asset_index",
filter_id_types={"filter_action"},
activate_operator="poselib.apply_pose_asset",
drag_operator="poselib.blend_pose_asset",
)
drag_op_props.release_confirm = True
drag_op_props.flipped = wm.poselib_flipped
activate_op_props.flipped = wm.poselib_flipped
```

Asset Browser: Python mixin utility for category-specific panels

Using this mixin for a panel definition, it's possible to set in which
categories the panel should appear. This is used by the Pose Library
add-on.

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.

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: 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.

Add support for RISC-V architecture

* On RISC-V GCC 10.3 does not define __GCC_HAVE_SYNC_COMPARE_AND_SWAP_n.

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

Cleanup: improve comments, remove debug printf

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

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

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.

Fix: crash when creating new node links

This was a regression in rBc27ef1e9e8e663e02173e518c1e669e9845b3d1f.

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.

Revert "Keymap: use D-Key for view-pie menu"

This reverts commit f92f5d1ac62c66ceb7a6ac1ff69084fbd5e3614a.

See: T89757 for rationale for reverting this change.

Keymap: use Alt-Q instead of D for transfer mode operator

This now works in all modes (not just sculpt) and activates on press
instead of release. See design task T89757.

Fix: missing null check

This was a regression in rB3b6ee8cee7080af200e25e944fe30d310240e138.

Geometry Nodes: dim links whose start and end sockets are not visible

This makes node trees with long links that cross other nodes easier to work with.
Dimmed links will be ignored by various modal operators like cut and reroute insertion.

Cleanup: replace BLI_assert(!"text") with BLI_assert_msg(0, "text")

This shows the text as part of the assertion message.

Cleanup: clang-format
