T-Tracer & Data Recording v1.1: UL PHY trace modularization and recording
enhancements

Based on the plan with @schmidtr  and @roux-cedric, we agreed to enhance
the data recording in two phases:

- Phase 1: Update Data Recording framework to get All internal Massive
  Updates and enhancements through the whole framework public
- Phase2: Restructure T-Tracer Apps and remove all Mems in gNB and UE
  Softmodems to Get data on T-tarcer Apps for all activated Messages
  symbol-by-symbol, and related Meta-data, then do the aggregation on
  the T-tracer App. So, there is No Memory Creation at all on the 5G NR
  Stack.

This Merge Request is for Phase 1. We address the comments given in: !3632

Summary: Refactor T-Tracer instrumentation for UL PHY data capture and
improve the data recording application (v1.0 → v1.1). This MR extracts
inline T() macro calls into modular wrapper functions, adds Unix timestamp
fields to trace messages, implements a 4-state shared memory protocol for
gNB/UE tracers, and delivers an improved synchronized recording architecture
in Python.

Changes:
- T-Tracer: Modular UL PHY trace wrappers
  - Add T_messages_creator.c/.h with 7 wrapper functions (log_ul_fd_dmrs,
    log_ul_fd_chan_est_dmrs_pos, log_ul_fd_pusch_iq,
    log_ul_fd_chan_est_dmrs_interpl, log_ul_payload_rx_bits,
    log_ul_payload_tx_bits, log_ul_scrambled_tx_bits) and a static
    log_ul_common() helper
  - Register T_messages_creator.c in the T library CMake build
  - Update T_messages.txt definitions: Remove string timestamps and get
    time stamp directly from sending_time of T-macro.
  - PHY: Replace inline T() calls with wrappers
  - gNB (nr_ulsch_demodulation.c, nr_ul_channel_estimation.c,
    phy_procedures_nr_gNB.c): replace inline T() calls with
    T_messages_creator wrappers
  - UE (nr_ulsch_coding.c, nr_ulsch_ue.c): replace inline T() calls with
    log_ul_payload_tx_bits and log_ul_scrambled_tx_bits wrappers
  - Remove deprecated log_tools.c/.h and its CMake reference

- T-Tracer gNB & UE apps: Enhancements
  - Implement 4-state shared memory protocol (WAIT → CONFIG → RECORD → STOP)
    for coordination with the data recording app
  - Add event_trace_msg_ul_data struct with 27 UL metadata fields
  - Refactor event loop to poll()-based with proper signal handling
  - Separate project IDs (gNB=2335, UE=2336) and ftok paths for independent
    shared memory segments
  - Update shared memory sizing: Limit number of records to
    NUM_MESSAGES_PER_SLOT=5, 100 slots

- Data Recording App v1.1
  - Improved architecture with thread pool and barrier synchronization
  - Frame/slot-based message grouping with per-slot validation
  - atexit/signal-based cleanup for graceful shared memory detach
  - Delete legacy data_recording_app_v1.0.py

- Library improvements
  - config_interface.py: remove legacy YAML config reader, streamline to
    JSON-only
  - shared_memory_interface.py: new module for shared memory
    attach/read/protocol
  - wireless_parameters_mapper.py: new module for NR parameter mapping
  - data_recording_messages_def.py: updated message definitions for
    27-field struct
  - sigmf_interface.py, sync_service.py, common_utils.py: remove unused
    imports and dead code

- Documentation
  - Update data_recording.md for v1.1 architecture and usage
