Do not emit unused fields in RDG source (#48426)

* Do not emit unused fields in RDG source Do not emit unused private fields for HTTP verbs that are not used by any of the user-code endpoints. Resolves #48381. * Move verbs to incremental pipeline Use another incremental pipeline to produce the HTTP verbs. * Add custom comparer Add custom comparer for endpoints by their HTTP method.
