see https://dev.mysql.com/doc/refman/8.0/en/innodb-row-format.html

when creating a table can we specify the dynamic format like CREATE TABLE t1 (c1 INT) ROW_FORMAT=DYNAMIC;?

refs #16810 to avoid row size too large error.

We'd need to check that this works on all MySQL or not sure if we need to check whether dynamic row format is supported or whether some MySQL maybe don't support it.
