MDEV-28599 EXCHANGE PARTITION on view causes ER_CHECK_NO_SUCH_TABLE instead of ER_WRONG_OBJECT
ER_CHECK_NO_SUCH_TABLE was raised because a view does not have the corresponding TABLE instance connected to TABLE_LIST and the server interprets the absence as the absence of the table itself. To fix the problem, we add a check to ensure that the target table to be swapped with a partition is not a view. Reviewed by: Nayuta Yanagisawa
