Subject: Add QPlatformSurface::screen() const

Classes inheriting QPlatformSurface need to return the QPlatformScreen
to allow the platform integration plugin to know information about the
used screen by the surface.

QPlatformSurface and QPlatformWindow had the same function defined, but
it was not possible to call it without casting the QPlatformSurface
pointer.
