Refactor set_tdd_config_nr to use frame_structure_t and tdd_period_config_t

Browse Source 
* assuming num_dl_slots and num_ul_slots are including also
  slots with dl/ul symbols respectively
* refactor set_tdd_config_nr
* moved function to MAC
* fill max_num_of_symbol_per_slot_list depending on slot type
* use new set_tdd_config_nr in stack
* minor refactor in config.c to improve readability (scs)
