Refs #24267 -- Implemented lookups for related fields

Browse Source 
Previously related fields didn't implement get_lookup, instead
related fields were treated specially. This commit removed some of
the special handling. In particular, related fields return Lookup
instances now, too.

Other notable changes in this commit is removal of support for
annotations in names_to_path().
