- when CU is used, UE ID data is filled as GNB_UE_ID_E2SM with
  CU UE ID value included

- Fix 4G and 5G discrepancy in TLV padding requirements: 4G does not
  need padding, whereas 5G needs, so make separate set of function for
  padding for NR
- Fix packing/unpacking for (n)FAPI PARAM and CONFIG.request/response
  messages
- Handle message padding to next 32-bit boundary, as per SCF
  specification in packing and unpacking functions
- Account for message header size upon receiving message in PNF and VNF

  can compile the target ldpc_generators and generate_T with cross-compiler

Testing on Neoverse N1 (Ampere 3GHz). Tested only on a subset of phy-simulators.

- Changes:
- use SIMDE consistently
- adaptations of LDPC decoder generator for ARMv8 performance
- SIMDe modifications of Intel CRC to allow for aarch64 build.
  optimizations for 128-bit to improve performance of LDPC encode/decode
  on aarch64 (Neoverse 1)
- added BG2 files for 128-bit ldpc encoder (aarch64)
- testing on Xeon
- testing on x86
- minor changes to build/run on x86
- change in crc.h after returning to aarch64
- removed some warning in ldpc decoder generator for x86_64
- char
- Delete irrelevant constants
- Correctly declare variables
- Define stdbool for all architectures
- Remove definition of _MM_SHUFFLE and use SIMDE_MM_SHUFFLE
- Remove commented code
- Fix CMakeLists.txt
- Include SIMDE avx2 functions in tools_defs.h
