Remove deprecated/removed InnoDB variables - innodb_large_prefix, innodb_file_format

[eRadical]

There are a lot of deprecated variables in MySQL/InnoDB/MariaDB. Example: MDEV-23397.

Filling ticket to compile a full list of deprecated variables but used by this role.
Then I'll follow up w/ a pull req.

These are my findings:

• expire_logs_days - is deprecated in MySQL in favor of binlog_expire_logs_seconds which defaults to 30 days, in MariaDB they're related as changes in one adjusts the other one - I think we should keep binlog_expire_logs_seconds and compute from mysql_expire_logs_days
• symbolic-links - is deprecated in MySQL, not deprecated in MariaDB - I think we ought to remove it
• innodb_large_prefix - deprecated in both - we ought to remove it completely
• innodb_file_format - deprecated in both - we ought to remove it completely

Also I thin pid-file should also be deprecated as it can be absent when SystemD is used.

@geerlingguy thoughts?

I'm okay with all those changes—the only one I think could be weird is symbolic-links. Not sure if people use it much (I don't... but I can't speak for all users of the role).
