bugfix: put constants in correct file

The RLC tests were not compiling because of the include of

    openair2/RRC/NR/rrc_gNB_radio_bearers.h

by

    openair2/LAYER2/nr_rlc/nr_rlc_entity.h

which does not seem correct/necessary to start with.

The only thing needed by nr_rlc_entity.h from rrc_gNB_radio_bearers.h
is MAX_DRBS_PER_UE which can be defined in common/platform_constants.h
like NGAP_MAX_PDU_SESSION.
