Add Reason to removeRemoteInput Logs

This CL adds removingRemoteInput reason to the logs to surface healthy and unhealthy removeRemoteInputFlows.
Healthy Flow:
1. RemoteInputViewController#sendRemoteInput
2. RemoteInputView#onDefocus#onDefocus
3. RemoteInputView$WindowInsetAnimation#onEnd
4. RemoteInputView#onDetachedFromWindow
Unhealthy Flow would be:
1. RemoteInputViewController#sendRemoteInput
2. RemoteInputView#onDefocus
3. RemoteInputView#onDetachedFromWindow
4. RemoteInputView$WindowInsetAnimation#onEnd
