MDEV-16851 On schema mismatch in IMPORT TABLESPACE, display ROW_FORMAT in clear text
This is motivated by Oracle MySQL Bug #27542720 SCHEMA MISMATCH
- TABLE FLAGS DON'T MATCH, BUT FLAGS ARE NUMBERS
but using a different approach.
row_import::match_schema(): In case of a mismatch, display the
ROW_FORMAT and optionally KEY_BLOCK_SIZE of the .cfg file.
