Android: Add preliminary support for child windows

Update the manual test case for embedded windows to have
native window on Android.

There are still some sharp corners, for example:

* The windows are implemented with SurfaceViews, which makes
  z-ordering with multiple of them a bit tricky. The Surfaces
  they instantiate are basically z-ordered to either be below
  everything, with a hole punched in the window, or on top of
  everything, with the Surfaces created later on top of the
  ones created earlier. Also, with the foreign views it looks
  like the native view is on top of the Surface, because it
  is created later. And since the child windows create their
  Surfaces before the parent, they would be behind the parent
  window, currently circumventing this with letting the
  parent be z-ordered behind everything, and the children
  on top of everything. A follow up commit addresses this by
  changing the native view class to TextureView when multiple
  windows are present.
* Parent window always gets the touch events - fixed in
  a follow up commit
* If a child window has a text edit, it does not receive
  focus when clicking on it
