NR UE: add support for continuous frequency offset compensation (in particular NTN LEO Doppler)

- move function add_noise() to file
  openair1/SIMULATION/TOOLS/phase_noise.c
- refactor (co)sinus calculation out of phase_noise() into get_sin_cos()
  in nr_common.c
- NR UE: continuously estimate the frequency offset using PBCH DMRS
- NR UE: add command line parameter --initial-fo to specify known
  initial frequency offset
- NR UE: add support for continuous DL frequency offset compensation
  --cont-fo-comp
- NR UE: add support for continuous UL frequency offset
  pre-compensation. Depending on the main source of frequency offset,
  pre-compensate the UL frequency offset (FO) accordingly. Therefore
  modify the flag --cont-fo-comp to accept an integer value, where
  * 1 specifies, that the main FO contribution comes from the accuracy of the local oscillator (LO)
  * 2 specifies, that the main FO contribution comes from Doppler shift
- NR UE: add PI controller to continuous frequency offset compensation
- rfsimulator: enable and correct NTN LEO doppler simulation
- use SIMD to speed up nr_fo_compensation()
- Extend NTN LEO example in RUNMODEM.md to include continuous Doppler
  compensation
- NR UE: in nr_adjust_synch_ue() extend the peak search to +/- cyclic
  prefix size, esp. for LEO NTN scenarios the timing drifts during
  initial sync, which is mostly compensated with
  --ntn-initial-time-drift. But there might be a residual time offset,
  and by extending the peak search window we make this more tolerant.
- NR UE: remove unused nr_slot_tx_offset, it is unused since commit
  f3e60a14
- NR UE: remove now unnecessary local variable
  update_ntn_system_information, directly use
  UE->ntn_config_message->update instead
