Make the qml/js matrix4x4 type more useful

This is used in Qt3D.  We also added these additional functions there
but for a nice user experience that doesn't kick up errors depending
upon the order in which QML modules are imported it would be useful to
add these new functions here too.

In the long term it would be nice if these QtGui type wrappers were in
a qtqmlgui module that was implicitly imported by both QtQuick and Qt3D.
