Adds RendezvousSession inside src/transport
RendezvousSession manages the initial connection between a commissioner and a device. During rendezvous a key pair is generated by SecurePairingSession under the hood. Embedders can listen to the different states of Rendezvous by implementing the RendezvousSessionCallback interface. The differents events are: * OnRendezvousConnectionOpened(); * OnRendezvousConnectionClosed(); * OnRendezvousError(CHIP_ERROR err); * OnRendezvousMessageReceived(System::PacketBuffer * buffer);
