[jOOQ/jOOQ#2682] Remove PolicyStatement again

PostgreSQL's feature where policies can apply to statements (or commands, such as SELECT, INSERT, UPDATE, DELETE) may be a bit overengineered for jOOQ. It would be very hard to re-implement the same semantics as PostgreSQL, in particular because we also cannot distinguish between USING and CHECK semantics easily.

As such, let's keep things simple and implement only ALL semantics.
