Android: Add function to change the stacking order in the layout.

This change enables us to reorder the stacking order used by the
layout. This is necessary if we want to influence the drawing order.

Lowering or raising views are done separately for native views and
Qt surface views, that is, the two different view "types" are moved
relative to other views of the same type and Native views are always
placed on top.
