QGuiApplication: fix handling of spontaneous events' modifiers

QtQuickTest synthetized events can have modifiers, but those modifiers
were not accessible globally, from QGuiApplication::keyboardModifiers
for instance.
eg. calling QML's TestCase::mouseClick with modifiers triggering a call
to QGuiApplication::keyboardModifiers did not give the expected result.

QtTest synthesised events can also have modifiers and those were
correctly handled by QApplication to set modifiers globally.

This fix moves the handling code from QApplication::notify to
QGuiApplicationPrivate::maybeSimulateModifiers and calls this function
from QGuiApplication::notify too.

The definite fix would be to do as suggested in the comment attached to
the moved code:
> Qt Test should not call qapp->notify(), but rather route the events
> through the proper QPA interface. This is required to properly
> generate all other events such as enter/leave etc.
