[SPARK-17394][SQL] should not allow specify database in table/view name
after RENAME TO
## What changes were proposed in this pull request?
It's really weird that we allow users to specify database in both from
table name and to table name
in `ALTER TABLE RENAME TO`, as logically we can't support rename a table
to a different database.
Both postgres and MySQL disallow this syntax, it's reasonable to follow
them and simply our code.
## How was this patch tested?
new test in `DDLCommandSuite`
