pathspec: add match_pathspec_depth()

match_pathspec_depth() is a clone of match_pathspec() except that it
can take depth limit. Computation is a bit lighter compared to
match_pathspec() because it's usually precomputed and stored in struct
pathspec.

In long term, match_pathspec() and match_one() should be removed in
favor of this function.
