LibOverride: expose `PROPOVERRIDE_LIBRARY_INSERTION` to py-defined properties.

This will allow add-ons to define Collection properties that support
item insertion in library override context.

LibOverride: support inserting items in py-defined (IDProp-based) collections.

Supporting IDProperty-based data storage here in a generic way is fairly
simple, unlike actual RNA data (DNA-based), for which getting a proper
generic way to duplicate them from within RNA is currently not really
possible.

Part of T79562.

RNA access: Add utils to search a collection item from its name, and get both item pointer and its index in the collection.

IDProperties: Add utils to duplicate content of one IDProp into another.

GPencil: Small tweak to Fill panel for Holdout

For gradient, put the parameter below both colors.

GPencil: Move Holdout parameter below Base Color

It's better keep this parameter here instead to put it at the end of the panel.

Fix T80982: Crash using custom orientations beside the first

UI: Gray out fade inactive geometry overlay slider when off

The slider should be inactive when the setting is turned off like
the wireframe slider.

Fix T61985: NLA Bake exception baking pose with non-pose selection

Cleanup: Fix clang tidy inconsistent parameter warning

UI: Always set curve fill mode inactive for object bevel type

The bevel type is a more useful check for graying out this property
because its effects will be apparent before choosing an object. Before,
the fill type property would only gray out with a bevel object selected.

Fix invert vertex group weight miscalculation for modifiers

Warp & weight vertex-group editing modifiers miscalculated vertex weight
inversion, the weights were multiplied before being subtracted from 1.

Ref D8241

Fix T80945: Build modifier not updating after outliner copy

Build modifiers linked or copied to objects from the outliner would not
animate until the file was saved and reopened due to a missing depsgraph
relations tag.

Cleanup: Use shorthand variables

We don't use the other variables in the sorting struct,
so we might as well use the panels directly.

Fix light rotation slider in Lookdev popover being disabled

Light rotation is supported both in world and view light orientation in
lookdev, so no reason to disable it.
