* feat: Hides prejoin screen on conference in progress event.

We enter the conference view as early as possible on conference in progress as the joined event can be late in a big conference.
Also, we show conference view only when joining is in progress, for example, the with the lobby enabled where we try to join but fail, we do not want to show the conference view for a fraction of a second before showing lobby screen.

This is a stop-gap approach to remove the AtlasKit notifications stack.

Instead of using a AK FlagGroup to render our notifications (Flag components)
in, create our own container and use a fake FlagGroupContext provider, which is
what FlagGroup uses to control what flags can be dismissed.

Since we now render all notifications, the web part has been refactored to make
sure all notifications get a timer.

Added animations
