LibVideo: Rename Status -> State in `PlaybackStatusChangeEvent` class

A bit of a bikeshed, but status sounds more like a result of an action,
and state sounds more accurate to what the `PlaybackManager` does.

The previous and current state fields of the `PlaybackStateChangeEvent`
are now removed, since they were unused (for now).

This is a lead-up to the refactoring of VideoPlaybackManager to make
that diff more legible.
