  1. sql: disallow schema changes for READ COMMITTED transactions 

    Due to how descriptor leasing works, schema changes are not safe in
weaker isolation transactions. Until they are safe, we disallow them.

This includes a small change to the grammar so that SET with empty key
names is consistently parsed, separate from the special SET ROW syntax.

Release note: None
