MDEV-33625 Add option --dir to mariadb-dump

Browse Source 
New option works just like --tab, wrt output (sql file for table definition
and tab-separated for data, same options, e.g --parallel)

Compared to --tab it allows --databases and --all-databases.
When --dir is used , it creates directory structure in the output directory,
pointed to by --dir. For every database to be dumped, there will be a
directory with database name.

All options that --tab supports, are also supported by --dir, in particular
--parallel
