Let users fil out if they use ATTR_EMULATE_PREPARES=true

Laravel will miss-behave in multiple ways with MySQL and PgSQL as documented in various issues and even PRs, because people try to get a fix in but _the_ recommendation right now is to *not* use it.

I figured it might save everyones time if ppl fill this out upfront because it's often takes some forth and back until users mention this.
