Disable copying and assigning of QEvent

Polymorphic classes should not be copied.

However, we do rely on event copying in our propagation logic. So, make the
members protected, don't delete them, using a dedicated macro.

This way, QMutable*Event classes can be used to make copies.

Remove some last usage of copying of QInputMethod(Query)Events.
