Add mysqli exception mode

[kamil-tekiela]

This PR changes the MysqliDriver to use exception mode just like PDO does. I tried not to make too many changes and stick to the previous style. There was some dead code in executeUnpreparedQuery which I removed to make the change easier.

thanks, maybe we can remove the warning suppression (@) now too? other question is can we get the state before we set it and set it back after connecting?

It also seems that MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT is the default since php 8.1, that would mean we already get exceptions in this driver but doesn't catch them?

Thanks for pointing this out. I removed the error suppression.
We can get the state from mysqli_driver->report_mode but I don't see why we would need to do that.

Yes, that would be true. Hence, why the current code needs to be changed because it doesn't work as intended. I still like to set the error mode explicitly though.
