AV moderation does not work on brerakout rooms.

Since some of the options in the "breakoutRooms" config section no
longer apply, I moved the relevant ones to a new "participantsPane"
section.

* hideAutoAssignButton
* hideFooterMenu
* hideModeratorSettingsTab
* hideMoreActionsButton
* hideMuteAllButton

Web and native

- implement breakout-rooms
- integrated into the participants panel
- managed by moderators
- moderators can send participants to breakout-rooms
- participants can join breakout rooms by themselve
- participants can leave breakout rooms anytime

Created Reusable components for:
- ListItem - used by participants list and lobby participants list
- ContextMenu - used by participant context menu and advanced moderation context menu
- Quick action button - used by quick action buttons on participant list items

Moved participants custom theme to base/components/themes

Created reusable button component for all participants pane buttons (Invite, Mute All, More)

Moved web components to web folder

Moved all styles from Styled Components to JSS

Fixed accessibility labels for some buttons

Removed unused code

Updated all styles to use theme tokens

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
