Subject: [PATCH] Fix missing Outliner selection syncing on "Select Hierarchy"

Adds syncing to a few operations that change selection, to avoid some
annoyances (like drag and drop of hierarchy to a different collection
only linking the parent to the collection).

Note that there's further refinement work for selection syncing in
D5572, but is awaiting some code design decisions. Meanwhile such quite
annoying issues should be fixed.

Addresses T75610.
