Fix T88499: Copy data path operator does not consider library affiliation

When using the operator `ui.copy_data_path_button(full_path=True)` ({key
ctrl shift Alt C} on hover) the copied path does not consider the
library origin. That means that when there is a name clash the data path
is not accurate and refers to the local item instead.

This patch adds the library (if the ID is linked) of the returned string
from RNA_path_full_ID_py.

bpy.data.objects["Cube", "//library.blend"] instead of
bpy.data.objects["Cube"]

note: parsing this happens in
pyrna_prop_collection_subscript_str_lib_pair_ptr
