Review comment:
> but the effect of this change is to disallow EXTERNAL when LOCATION is
not present.
This is already the case before this PR. The error message is pretty clear
about it: `CREATE EXTERNAL TABLE must be accompanied by LOCATION`. The change
here only loose the restrictions.
I include this change because otherwise tests that use `CREATE EXTERNAL
TABLE ... LOCATION` without USING or STORED AS are failing.
