Add support for all database engines that Moodle supports

[luisdev]

I tried installing version v3.9.2 (2022011400) of this Growth report on a v3.9.12+ instance of Moodle that runs on s MS SQL Server 2012 database using the Moodle SQLSRV driver.

After installing the plugin I got lots of errors like the following:
Message: [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]'FROM_UNIXTIME' is not a recognized built-in function name.

The 'FROM_UNIXTIME' function is not compatible with MS SQL Server. All database queries should be done via the Moodle database layer, not via engine specific functions like FROM_UNIXTIME().

HI @luisdev,

THX for your input.

Currently this plugin only supports MYSQL, MariaDB and PostgreSQL. As i do not have a SQL or Oracle DB server, I wait for issue 92 and issue 128 to have some testing available.
