Set TaskSnapshotWindow no InputChannel.

Browse Source 
TaskSnapshotWindow has no need to process any input events.
If it has a valid InputChannel but no InputEventReceiver,
it won't receive events sent by InputDispatcher like TouchModeEvent.
This may cause an ANR.

Test: when TaskSnapshotWindow is showing, verify that touch on
Notification shade won't trigger ANR on TaskSnapshotWindow.
