QtGui: Use single precision for mouseMove detection
QGuiApplication::lastCursorPosition is a QPointF, and (at least on macOS)
compares always different from the QPointF stored in the event. This
might be due to the translation from system coordinates to QPointF
introducing noise.
The result is that even a simple button press causes mouseMove events
to be delivered.
To prevent this event noise, overload equality operators for the special
QLastCursorPosition type when comparing with QPointF to explicitly use
single precision comparison.
Pick-to: 6.5 6.4 6.2
Fixes: QTBUG-111170
