Refactor NRRCConfig

* the goal of this function is to initialize and configure the RAN Context
* the goal of get_options is to get command line options
* this commit aims at making the implementation more consistent
* move initialization of RC.nb_nr_CC to this function
* cleanup redundant initializations of RC.nb_nr_macrlc_inst outside NRRCConfig
* cleanup redundant initization of RC.nb_nr_macrlc_inst from getter function (get_node_type)
* cleanup RC initialization in RCconfig_NR_L1
* removed redundant log lines (print number of instances in NRRCConfig only)
* do RC init after getting CL options and configuration
* get_node_type shall access configuration only, not RC context
* NRRCConfig shall be called only once: made it thread-safe
