Print out error position for some more DDLs

The following commands gain some information about the error position in
the query, should they fail when looking at the type used:
- CREATE TYPE (LIKE)
- CREATE TABLE OF

Both are related to typenameType() where the type name lookup is done.
These calls gain the ParseState that already exists in these paths.
