Pass window type to the InputWindowHandle of embedded window
A windowless SurfaceControl could grant input via
IWindowSession.grantInputChannel, but other window may receive the
obscured events because of the type value of input window is always 0.
The obscured or partially obscured flag indicates that the window
received this motion event is wholly or partially obscured by another
visible window above it.
We have to filter out the trusted overlap so the motion event could
properly dispatch to the view if it is a security sensitive application.
Bug: 156063505
Test: enter split window mode and check the motion event
