IMPALA-7679: Improve error message when adding NULL column in CTAS, CREATE VIEW and ALTER VIEW

This patch improves the error message to be more helpful when inserting
a NULL column in CTAS, CREATE VIEW, and ALTER VIEW  without an explicit
cast due to the inability to infer the column type.

Testing:
- Added new FE tests
- Ran all FE tests
