After this commit, only the RNTI is used as an identifier in the MAC.
Further, it removes some module_id, but a lot of them remain (the goal
to remove all is still far from us)

Merge remote-tracking branch 'origin/NR_removing_calculate_preferred_tda' into integration_2022_wk21

UHD documentation: "A tune request instructs the implementation how to
tune the RF chain."

This commit makes this configurable, from nr-softmodem, nr-uesoftmodem,
lte-softmodem, and lte-uesoftmodem.

In the past, setting k2=2 for 5ms TDD periods resulted in increased ping
RTT and/or reestablishment requests. These problems do not appear
anymore, and we can allow k2=2.

In the past, activation of slot 0 (i.e., after the switch UL->DL)
resulted in many retransmissions. This does not seem to be the case
anymore, and we can therefore activate slot 0 also in TDD.

- Introduce generic get_mcs_from_cqi() that gets MCS for a particular
  CQI
- Set MCS after receiving CQI
- Distinguish "global" max MCS from UE-measured max MCS
