MDEV-19514 preparation: Extend innodb.innodb-change-buffer-recovery

Browse Source 
Test innodb_read_only startup (which will be refused after a crash),
and test also innodb_force_recovery=5, and extract some change buffer
merge statistics. Omit any statistics about delete (purge) buffering,
because purge could happen at any time.

Use the sequence storage engine for populating the table.
