GIN support for @@ and @? jsonpath operators
This commit makes existing GIN operator classes jsonb_ops and json_path_ops
support "jsonb @@ jsonpath" and "jsonb @? jsonpath" operators. Basic idea is
to extract statements of following form out of jsonpath.
key1.key2. ... .keyN = const
The rest of jsonpath is rechecked from heap.
Catversion is bumped.
