Handle the mouse events in the window itself

It is now not the screen that handles all of the events and relays
them to individual windows, but the window elements themselves.

This allows us to get rid of manual window targeting logic and let
the browser do its job.

Fixes: QTBUG-107217
Pick-to: 6.5
