Use Diesels MultiConnections Derive (#6279)

* Use Diesels MultiConnections Derive

With this PR we remove almost all custom macro's to create the multiple database type code. This is now handled by Diesel it self.

This removed the need of the following functions/macro's:
 - `db_object!`
 - `::to_db`
 - `.from_db()`

It is also possible to just use one schema instead of multiple per type.

Also done:
 - Refactored the SQLite backup function
 - Some formatting of queries so every call is one a separate line, this looks a bit better
 - Declare `conn` as mut inside each `db_run!` instead of having to declare it as `mut` in functions or calls
 - Added an `ACTIVE_DB_TYPE` static which holds the currently active database type
 - Removed `diesel_logger` crate and use Diesel's `set_default_instrumentation()`
   If you want debug queries you can now simply change the log level of `vaultwarden::db::query_logger`
 - Use PostgreSQL v17 in the Alpine images to match the Debian Trixie version
 - Optimized the Workflows since `diesel_logger` isn't needed anymore

And on the extra plus-side, this lowers the compile-time and binary size too.
