6432: Do not pause or display media notification when all media is muted. r=pocmo a=everett1992

Firefox preview will display a notification and request audio focus even
when the playing media is a muted gif, webm or other 'lite' media.

My goal is to stop requesting audio focus when the media is not playing
audio.
 - I only considered muted media. I ignored media with volume == 0.0,
 and media with audioTrackCount == 0. I'm not _sure_ that
 audioTrackCount 0 means the media is not playing sound. A similar
 commit could track and check those values.
 - I added the check for muted audio in MediaAggregateUpdaterTest
 because I am nnoyed by the notifications firefox creates if I leave a
 page with a webm in an open tab. I think aggregating player state to
 NONE will disable the notification. People won't be able to play/pause
 muted media from a notification, but I don't expect that's a common
 usecase. The check can be moved to MediaStateDelegate to avoid chaning
 the notification behavior.

6547: Closes #4397: Migrate feature-readerview to browser-state r=pocmo a=csadilek

@pocmo Super happy with how the middleware worked out. It basically maps state to other (action/state), as relevant to reader view e.g. the url has changed -> a new reader check is required.

The other cases handled by the middleware are:
- User opens a tab via the context menu (may or may not switch to it directly)
- A new tab is selected
- A tab is removed (see comment in middleware)

All other functionality remains the same. Diff is big mostly because of test refactorings :)

I found another way that allows us to remove all reader state from the session right away! I am storing the state in the snapshot directly (same as `engineState`) and let the `SessionManager` deal with adding/deleting it based on the state in the store. This way we don't need to pass the store along to the serializer / session storage.
