This enables build_oai to detect if the output terminal supports colors.
If it does, it will use colors in its output. If it does not, it will
just print the text, without color codes, improving legibility.

Merge remote-tracking branch 'origin/break_dci_processing_function_in_smaller_pieces' into integration_2023_w41

- Remove calloc from convert_csirs_pdu function, change return value
  from 'nfapi_nr_dl_tti_csi_rs_pdu_rel15_t *' to
  'nfapi_nr_dl_tti_csi_rs_pdu_rel15_t' to not require call to 'free()'
- Set parameter pointer as const as it's not modified
- Remove cast to fapi_nr_dl_config_csirs_pdu_rel15_t in csi_rx.c as
  ue->csirs_vars[gNB_id]->csirs_config_pdu is already of type
  fapi_nr_dl_config_csirs_pdu_rel15_t.
- Remove casted parameter in call to convert_csirs_pdu and replace with
  csirs_config_pdu obtained earlier from
  ue->csirs_vars[gNB_id]->csirs_config_pdu.

It is *normal* to receive new CellGroupConfigs from the DU, hence a
warning is not warranted.

- forward capabilities to update CellGroupConfig
- Do not require measConfig/cG_ConfigInfo to be NULL, but ignore them,
  as it is not implemented

The RRC container is to be handled by the msg handler in
mac_rrc_dl_handler.c. Therefore, don't forward the RRC message, but copy
it into the message so the handler can take the action.

The two hardcoded PLMNs are never executed: they are in an if(0) block
