IMPALA-9652: CTAS doesn't respect transactional properties

Because of a bug the INSERT part of a CTAS statement didn't
run in a transaction and it just put the new files under the
root directory of the table. This didn't cause too much problems
because there couldn't be any concurrent operations as the table was
under construction. However, this behavior is not working particularly
well in the context of replication, as the notification event needs
a transaction id.

With this fix the INSERT operation runs in a transaction and the new
files are created under a delta directory.

Testing:
* Added CTAS statements and SHOW FILES <tbl> queries to acid-insert.test
  Check if the files are created in a delta directory, if so, then
  the INSERT must have been running in a transaction.
