adjust ACL owners for REASSIGN and ALTER OWNER TO

Browse Source 
When REASSIGN and ALTER OWNER TO are used, both the object owner and ACL
list should be changed from the old owner to the new owner. This patch
fixes types, foreign data wrappers, and foreign servers to change their
ACL list properly;  they already changed owners properly.

BACKWARD INCOMPATIBILITY?
