Fix T84373: Overrides : shapes keys driven by armature don't work on second instance.

Code generating override operations would not deal properly with Pointer
RNA properties, trying by default to use and check pointers' names
properties like it does with items of a collection.

However, using name property in pointer RNA property case makes no
sense, so specialize the `no_prop_name` flag for each case (pointer or
collection).

here, since second override would generate local data-blocks with
different names than the linked data ones, name matching would fail and
breck handling of override diffing in shapekeys.

Note that shape keys are the only one concerned by that problem, since
other embedded IDs (root node trees and master collections) are fully
real ones, so they always get the same names.
