We don't plan to send both (camera and screen) streams at once, but we
do plan to align with web and have both streams at the same time, with
the camera being muted when we start screen sharing.
* fix(connection-status): remove unused participant connectionStatus.
Always use trackStreamingStatus now that legacy endpoint based signaling has been removed.
* remove the check for source-name signaling.
Default to source-name signaling always.
* Remove the check for multi-stream mode.
Make that the default mode and remove the support for legacy SS mode.
* Remove presenter mode.
