[Columnar] Bugfix for Columnar: options ignored during ALTER TABLE rewrite

[yxu2162]

A fix for this issue: Columnar: options ignored during ALTER TABLE rewrite #5927 The OID for the temporary table created during ALTER TABLE was not the same as the original table's OID so the columnar options were not being applied during rewrite.

The change is that I applied the original table's columnar options to the new table so that it has the correct options during write. I also added a test.
