Move input change event handling out of TVInputManager

HDMI input change event should be handled best in TIS implementation
of HDMI input since the input change request from TV/other device
needs to be properly coordinated. This requires the listener be
moved the input service.

Provided an interface in HdmiTvClient for the input service to access
the API through getSystemService(Context.HDMI_CONTROL_SERVICE).
