Upper-layer PDCP packet dispatcher.

Receives SDUs from the module above -- Ip2Nic, or NrSdap where SDAP is present -- looks up the toTxEntity gate of the PDCP TX entity serving that DRB, and dispatches the packet to it. Purely a dispatcher: TX entities are established by Ip2Nic/SDAP, and wired and registered in this module's routing table by BearerManagement. Collects processed SDUs from the RX entities and sends them back up.
