QGestureManager: port to ranged-for [2/6]

The enclosing iterator-based loop: the loop body doesn't modify the
`m_objectGestures` QMap (the original loop was using const_iterators),
so port to ranged-for by using asKeyValueRange().

The foreach loop: the loop body doesn't modify the `gestures` QList, so
a simple port to ranged-for.
