MDEV-14882 mysql_upgrade performs unnecessary conversions back and forth 

avoid round-robin conversions, if the column is MODIFY-ed,
it should always be modified to its final definition, not to some
intermediate state.

also avoid other unconditional changes, like
  ALTER TABLE event DROP PRIMARY KEY;
  ALTER TABLE event ADD PRIMARY KEY(db, name);
