Create and destroy ParticipantDisplayItems based on call participants

Browse source 
The ParticipantDisplayItems were created and destroyed based on the peer
connections. Now a ParticipantDisplayItem of "video" type is associated
to a call participant, while an additional item is created and destroyed
depending on the state of the screen peer connection of the call
participant.
