Use a global WatchManager for settings

Browse source 
Fixes https://github.com/vector-im/riot-web/issues/8936

Watchers are now managed by the SettingsStore itself through a global/default watch manager. As per the included documentation, the watch manager dispatches updates to callbacks which are redirected by the SettingsStore for consumer safety.
