[PATCH] MDEV-22659: Create one single unified and optimal logrotate config

Replace mysql-log-rotate.sh and debian/...mysql-server.logrotate with one
new unified and well documented version.

Name is mariadb.logrotate.in as in 10.6 branch we use now the 'mariadb'
name, and use 'logrotate' to match the actual name of the utility, and
use '.in' instead of '.sh' as this is not a shell script but a template
file.
