Extend :: syntax to function calls for pg_catalog types

- Allow FuncCall node types to use :: syntax when casting to pg_catalog types
- Successfully converts CAST(public.gen_random_uuid() AS text) to public.gen_random_uuid()::text
- Updated pg-catalog test snapshot to reflect new behavior
- All 267 test suites pass with no regressions
