Arrange to cache FdwRoutine structs in foreign tables' relcache entries.

Arrange to cache FdwRoutine structs in foreign tables' relcache entries. This saves several catalog lookups per reference. It's not all that exciting right now, because we'd managed to minimize the number of places that need to fetch the data; but the upcoming writable-foreign-tables patch needs this info in a lot more places.
