Fix: Add missing TBB define to geometry module

rename to *Impl

support converting VMutableArray to VArray

add mutable virtual array

rename to VMutableArrayImpl

cleanup

more virtual array tests

Assets/UI: Improve asset library Preferences UI

* Open File Browser when pressing "Add Asset Library". This just makes sense,
since users have to select a directory for the asset library anyway.
* Move '+' icon back to the right side of the box. Then it is right under the
'x' icons for each indivdual library, which seems like the more natural
place.
* Correct tooltip for the "Add Asset Library" operator.
* Mark empty asset library name or paths field in red, to make clear that these
need to be set.

Fix: Asset using selection in instances to points node

Geometry Nodes: Add Instances to Points Node

This node takes a geometry set with instances as input and outputs
points located on the origins of the top level of instances in the
geometry set (not nested instances). It also has position and radius
inputs to allow overriding the default, and a selection input to only
generate points for some instances.

The use case for this node is a method to use geometry proximity on
instance origins, but in a more generic way that is flexible and useful
in other situations.

Fix: Empty geometry nodes input menu with legacy nodes enabled

Caused by a misplaced comma at the end of a line in Python.

Fix: Support swapped inputs properly in trim curve node

Previously, when the start input was greater than the end input,
the spline was resized to a single point. That is correct, but the
single point wasn't placed properly along the spline. Now, it is
placed according to the "Start" value, as if the trim started, but
couldn't continue because the "End" value was smaller.

This behavior is handled with a separate code path to keep each
simpler and avoid special cases. Any cleanup to reduce duplication
should focus on making each code path shorter separately rather
than merging them.

Also included are some changes to `lookup_control_point_position`
to support cyclic splines, though this single-point method is still
disabled on cyclic splines for consistency.
