Adaptation of MAC TA procedures to the design of handle_dlsch

- introduced new parameter in nr_ue_dl_indication for UL time alignment
- moved TA timer logic one level up so that now is executed every slot
- set timer value to 80 slots to cope with the sl_ahead design
- introduced new TA-related members to gNB MAC instance struct
