services: MySQL: Deprecate 'mysql-service'.

* gnu/services/databases.scm (mysql-service): Define in terms of DEFINE-DEPRECATED.
* gnu/tests/databases.scm (%mysql-os): Adjust accordingly.
* doc/guix.texi (Database Services): Adjust the MariaDB/MySQL section to
document MYSQL-SERVICE-TYPE instead of MYSQL-SERVICE.  While at it, document
the EXTRA-CONTENT field.
