Track presence state per-device and combine to a user state. (#16066)
Tracks presence on an individual per-device basis and combine
the per-device state into a per-user state. This should help in
situations where a user has multiple devices with conflicting status
(e.g. one is syncing with unavailable and one is syncing with online).

The tie-breaking is done by priority:

    BUSY > ONLINE > UNAVAILABLE > OFFLINE
