Norman Feske 3394be9464 Clean up scout widgets
This patch integrate the scout widgets with Genode's new API headers
'util/geometry.h', 'os/surface.h' and 'os/texture.h'. Thereby, we get
almost rid of the platform-abstraction shim that was never used anyway.

Furthermore, it extracts the parts that are worth reusing from the
scout implementation to the public location 'demo/include/scout'.
