Adding the SurfaceView on splash screen thread.

The SurfaceView of the AVD icon should be create on splash screen
thread instead of worker thread, this can guarantee that the first
frame of the FrameLayout and AVD will be draw at the same frame.
And it also become faster by combining two view in same traversal
together.

Also stop the AVD animation after splash screen window removed.

Bug: 195736516
Test: verify no more Choreographer#doFrame on splash screen thread
after splash screen window removed.
