QGuiApplication: do not emit deprecated signals

Browse Source 
... when QT_DISABLE_DEPRECATED_BEFORE is past the deprecation version.

This commit actually stops using the deprecated signals when we build
Qt with QT_DISABLE_DEPRECATED_BEFORE >= 0x060000. Otherwise we will
get a compilation error because the signals will be removed.
