feat(notifications): NotificationsContainer native updates

Use our component instead of atlaskit
Implement redesign
Add unmount animation
Change mount animation from external lib to CSS
Remove @atlaskit/flag
Remove react-transition-group
Add unmount animation on native
Remove AbstractNotification

* feat(notifications): native notifications UI updates

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

Renamed DrawerPortal to JitsiPortal

Redesigned notifications
Changed notification text and icons color and added collared ribbon

Only one notification will be displayed at a time on mobile.

Adds 1 liner notifications to mobile. Only the title is displayed. In
case the title is missing there's a fallback to the description.

Moves NotificationContainer to the toolbox and filmstrip container, so
that there's no need to manually calculate the positions.

The outer container is not necessary if 'justifyContent: flex-end' is
used with the absolute fill on the main container.
