fix tx_resume_ind_fifo messages sending bugs, rename associated function send_slot_ind() to what it actually does send_dl_done_to_tx_thread()

merge two reduntant and incoherent enums for rnti_type_t, make a macro to stringify properly instead of hardcoded side strings array

Simplify the intermediate struct nr_uplink_indication_t by passing only tx frame+slot
Simplify nr_scheduled_response_t by removing module id, CCid, ... that are there only to rediscover the mac storage structure head, pass directly the mac head pointer instead
fix bugs in ul_info.frame_rx + 1 that was missing %1024
add mutex mac_IF_mutex modifications verification of returned value to log errors if a error occurs
remove fill_scheduled_response() that was doing nothing useful
split nr_ue_dl_indication() implementation in two very differnt functions depending on the call purpose (ue scheduler or actual dl data processing), the API is kept as one nr_ue_dl_indication() unchanged, nevertheless this design is obscur
rework completly the access to mac->ul_config_request[slot]
    - make proper encapsulation of the data access, mutex, ... and proper API to create elements, iterators
    - kept general usage of this mutex protected storage as it is, even in useless cases (like inside processing of this given tx slot, so the consumer speaks to itself)
nr_ue_get_rach(): remove a hidden result data global variable to return explcitly computed value (in one place, it reveals we don't use the computed value, kept as it is)
nr_get_msg3_payload(): add a polling waiting state to wait the RRC thread sent the pdu to RLC (should be fixed better later)
simplify a bit ue->tx_resume_ind_fifo, add logs in error cases, coherency checks with the associated counter tx_wait_for_dlsch
this counter tx_wait_for_dlsch reduce it's visibility to be now local in main UE loop (UE_thread)
nevertheless, it should be simplified more (the pair tx_resume_ind_fifo/tx_wait_for_dlsch is a complex wiat to make a semaphore, and maybe we can entirely simplify the multi-threading by running in place when it is appropriate time instead of calling send_slot_ind() that is furthermore a wrong function naming
split nr_ue_scheduled_response() in nr_ue_scheduled_response_dl() and nr_ue_scheduled_response_ul(), the function is kept to minimize the code change
improve this function C code, by shortening long C lines

minor cleaning: move to static functions related to this MR when they can be static

* !2482 Trigger UL Failure if Ack of Msg4 not received and implement RA Contention Resolution timer in gNB
* !2484 function to harmonize handling of NAS registraction accept
* !2487 Rework PUCCH codec with c16_t type and functions to make readable code
* !2491 improvements for NR UE detaching
* !2499 Update L1sim and RFsim documentation
* !2500 Fix FAPI CoreSetType enumeration options after the fix on the description made by SCF
* !2489 NR UE improvements RRCSetup

- update explanation for noS1
- better help for nr-uesoftmodem options
- consistent writing of name "RFsimulator"
- remove LDPC section at end, is already referenced in doc/README.md

- Add TOC
- Better describe what RFsim does
- Remove misleading, wrong, unnecessary information
  * It is futile to mention --phy-test or other modes, RFsim works with
    all
  * Explaining how to ping is not the task of the RFsim documentation
    (that is what tutorials are for)
  * Remove useless/outdated build log information
- Add some more information on which flags to run
- Improve formatting, and minor clarifications

Merge remote-tracking branch 'origin/NR_UE_harmonize_NAS_registration_accept' into integration_2024_w01

improvements in UE detachment, including sending a message from NAS and signaling to MAC and fixing some memory leaks when terminating UE

SCF FAPI 222.10.02 had a bug on the description of CoreSetType:
0: CORESET is configured by the PBCH or SIB1
(subcarrier 0 of CRB0 for DMRS mapping)
1: otherwise (subcarrier 0 of CORESET)

That was fixed in SCF 222.10.04:
0: CORESET is configured by the PBCH or SIB1
(subcarrier 0 of the CORESET)
1: otherwise (subcarrier 0 of CRB0 for DMRS mapping)

That wrong description created a misunderstanding, to overcome it we "wrongly" added a third value. This commit fixes that and aligns the CoreSetType with FAPI 222.10.04

rework PUCCH codec with c16_t type, rewrite large parts of functions to make readable code. Not fixed parts that are using SIMD. No change, the code is still same block by block (variable visibility narrowed, declaration can be shifted)

- Do not list L1sim as a way of running OAI: it is untested, and might
  not work
- Reword the tutorial where necessary, remove outdated/wrong information
  (e.g., we don't test this mode AFAIK)

Implement RA Contention Resolution timer in gNB accordingly with 3GPP TS 38.321 Section 5.1.5 Contention Resolution

The UE will trigger new RA either with MAC CE C-RNTI or with new RRCSetupRequest:
- MAC CE C-RNTI: The ul_failure_timer will be reset
- RRCSetupRequest: New UE will be created and the previous one will be deleted
