MDEV-27214 Import with disabled keys corrupts meta-data like rows, in…

…dexes, ...

This bug was previously fixed in 10.6.11 by:
   MDEV-28327 InnoDB persistent statistics fail to update after bulk insert

Adding MTR tests only.

Also, fixing the old test for MDEV-28327 to make "mtr" reliably pass
with/without --mysqld=--innodb-stats-persistent=0, and with different page sizes,
as suggested by Marko.
