QFlags: add operator== and !=
It's a value type, and we don't need detours through implicit
conversions (which are a real disgrace, as they make nonsense like
`flags != 3.14` well-formed).
[ChangeLog][QtCore][QFlags] Added overloads of operator== and
operator!= between QFlags objects, and between a QFlags object
and an object of the flag's enumeration.
