Add calls to initialization and configuration functions for RLC and PDCP at nrUE for SA mode

-RRCSetupComplete successfully transferred to RLC of the UE now through SRB1, but not at the MAC yet.
-Needed to enable some additional elements for RLC config. at the gNB side (asn1_msg.c) so that the addition of the SRB does not fail at the UE.
 To verify if these are really required.
