QGestureManager: don't abuse a QMap for a set
The filterEvents() implementations used a QMap<GestureType, int> for
tracking whether a given type was already seen. The mapped_type was
completely unused.
Since the expected number of gesture types is very low, go directly to
QVarLengthArray, not QSet, as the reduced number of allocation will
dwarf the low overhead of O(N) search vs. O(1) for QSet or O(logN) for
QMap.
