QRasterPaintEngine: fix GCC 12 -Werror=array-bounds

Browse Source 
An enum variable can legally have values larger than the largest
enumerator, so GCC isn't wrong in warning about accesses out of
bounds. But we know that we don't OR enumerators of this enum
together, so tell GCC, too, by using a Q_ASSUME().

Pick-to: 6.3 6.2
Task-number: QTBUG-103923
