Fix T93353: Reload Library Override file loses Constraints, take II.

When adding `INSERT` operations over RNACollection items, rna diffing
code did not properly report the properties as not being equals.

This in turn triggered the 'purge unused exiting override properties'
mechanism, thus deleting the exitsting (valid) insert override property
operation.

NOTE: This should also be backported to 2.93, and probably 2.83.

Fix T93477: Viewport X-Ray is influencing snapping even in material mode

The default snap behavior to perform on tools and cursors is to the
final geometry and not edited geometry.

In snapping to edited geometry, there are some specific behaviors that
are not convenient in some cases. For example the general occlusion
test of X-Ray geometries during dragdrop.

This fix also resolves a regression for tools like measure and placement
that were also ignoring the snap to face in x-ray mode.

LibLink/Append: Port `bpy.data.libraries.load` to new `BKE_blendfile_link_append` module.

Note that this fully replaces the 'PyCapsule' storage of linked/appended items
in the python API code by the generic storage of items in the
`BlendfileLinkAppendContext` data.

Fix T93508: Shift+F1 to switch to asset browser randomly crashes

Geometry Nodes: Rename Curve Parameter, Add Index on Spline

- Rename the Curve Parameter node to Spline Parameter.
- Add "Index on Spline" to the node. This output is the index of

Asset Bundle Copy button: only report each external dependency once

The `ASSET_OT_bundle_install` operator only works when the blend file is
self-contained. It reports any external dependencies. Before this patch:

- every dependency was mentioned, even when it repeated the same
filename over and over again, and
- multiple dependencies were all mentioned in the error popup,
potentially filling the screen.

This is now resolved by:

- only reporting each external file once, and
- referring to the console when there are multiple external dependencies.

VSE: Disable interactivity in combined view

Combined view of timeline and preview causes seemingly unpredictable

Disable new features in this combined view, so behavior should be

LibLink/Append: tweak asserts in main BKE link/append functions.

Merge remote-tracking branch 'origin/blender-v3.0-release'

This includes adjustment of rBc12d8a72cef5 to the new path traversal code
introduced in rBe5e8db73df86.

BPath traversing: allow skipping weak library references

Add flag to `BKE_bpath_traverse_id()` and friends to skip weak
references (see below). This makes a distinction between "this blend
file depends on that file" and "this blend file references that file,
but doesn't directly use its data". This distinction is for the Asset
Bundle install operator, which refuses to copy the blend file when it's
not self-contained.

Weak references are those that are not directly used by the blend file,
but are still present to allow path rewriting. For example, when an
Asset is loaded its originating blend file is saved in
`ID::library_weak_reference`; this reference is purely for deduplication
purposes, and not for actually loading any data.

Fix T93442: Crash when proxy building is cancelled

If strip is removed while proxy is built, this causes crash when
building is finished. This happens because proxy anims are freed in
`SEQ_proxy_rebuild_finish()`.

Iterate over available strips and check if original strip still exists
by comparing `SessionUUID`.
