Add QQuickMatrix4x4, a way to specify a matrix transform in QML.

Add QQuickMatrix4x4 which makes it possible to specify a 4x4
matrix tranformation directly in QML instead of decomposing the
transformation into rotation, scale etc. It does NOT replace anything,
just adds a new way of specifying a tranformation of an Item.
