Support multiple native surfaces on Android.

Support for multiple native surfaces is needed by applications that need
to mix raster windows with GL windows.
Rework the raster and opengl implementation, get rid of eglfs and
fbconvenience dependencies.
Create a single android platform plugin.

[ChangeLog][Android] Rework the raster and opengl implementation.
