Add a get_tree_entry_path() variant in addition to
get_tree_entry_path_{mode,type,all}(). This is for those callers that
need neither the mode nor "enum object_type" parameters filled for
them.
There are callers here which don't need the "struct object_id" filled;
forcing callers to pass one just requires they create a throwaway
variable.
See the following commits for the introduction of such code that's
being modified here:
- shift_tree(): 68faf68938e (A new merge stragety[sic] 'subtree'.,
2007-02-15) for the shift_tree()
- tree_has_path(): 96e7ffbdc31 (merge-recursive: check for directory
level conflicts, 2018-04-19)
- init_notes(): fd53c9eb445 (Speed up git notes lookup, 2009-10-09)
- diagnose_invalid_oid_path(): 009fee4774d (Detailed diagnosis when
parsing an object name fails., 2009-12-07)
Those could potentially be refactored too, but I've got to stop at
some point, and right now I'm focusing downstream code that depends on
"mode" (or "enum object_type").
