refactor(rse): put MHU code in a dedicated file
To be able to use RSE comms without MHU, a first step is to disentangle
the rse_comms.c file with MHU code direct calls. This is done with the
creation of a new file rse_comms_mhu.c. New APIs are created to
initialize the mailbox, get max message size and send and receive data.
