Log/Dump data about RemoteInputActive

We need to investigate the impact of the RemoteInput on Keyboard opening issue to determine why the issue is happening and how to resolve it.

In order to do it:

1. We extend `NotificationContentView`'s dump to surface any issue happening in `stealFocusFrom`.
2. We log addRemoteInput and removeRemoteInput with `RemoteInputControllerLogger` to understand state changes in `mRemoteInputActive`.
