Distinguish room state and timeline events in embedded clients (#4574)

Browse Source 
* Distinguish room state and timeline events in embedded clients

This change enables room widget clients to take advantage of the more reliable method of communicating room state over the widget API provided by a recent update to MSC2762.

* Add missing awaits

* Upgrade matrix-widget-api
