Avoid window geometry jittering when changing geometry from JavaScript 

The QML API allowed only separate setting of geometry parameters which
causes flickering when all parameters need to be changed.
By exposing the setGeometry function it is possible to set all of these
at once using an imperative setGeometry call from JavaScript.

Note that bindings for x/y/width/height are still evaluated
sequentially, resulting in four calls to the platform window's
setGeometry. This patch only introduces an imperative workaround for
that issue.
