MDEV-23805 Make Online DDL to Instant DDL when table is emptybb-10.7-MDEV-23805
In ha_innobase::prepare_inplace_alter_table(), InnoDB should
check whether the table is empty. If the table is empty then
server should avoid downgrading the MDL after prepare phase.
It is more like instant alter, does change only in dicationary
and metadata.
Changed few debug test case to make non-empty DDL table
