STORED PROGRAMS

Problem: Logical backup files when restored causes error, when definer accounts
referenced in stored programs (backed up in .sql file) are not present on the
target server.

Issue: The above behaviour can be seen from 8.0.22 onwards after WL#14073 was
pushed.

Fix:
When --all-databases is specified, always first dump mysql database, which helps
referenced definer accounts to be restored first, before actual stored programs.
