feat(ctrace): decode compressed Armv8-M DWT packets

[thorstendb-ARM]

Summary

Add support for compressed Armv8-M DWT Data Trace PC Value and Data Address packets.

Changes

• Decode short, medium, and long DWT address payloads.
• Reconstruct omitted address bits from the corresponding DWT_COMP<n> value.
• Read comparator values from ctrace-run.yml register settings.
• Support comparator metadata from data and instruction-address ranges.
• Preserve existing Armv7-M packet handling.
• Keep the existing CSV and CTF schemas unchanged.
• Add unit tests and a synthetic Armv8-M integration trace covering:
  • short and medium PC Value packets
  • short and medium Data Address packets
  • missing comparator metadata
  • invalid payload sizes and PC match bits

The synthetic trace models PC compression using an instruction-address range and address compression using a data-address range.

Validation

• 194 unit tests passed
• 5 platform-specific unit tests skipped
• 15 integration tests passed

Checklist

• 🤖 This change is covered by unit tests (if applicable).
• 🤹 Manual testing has been performed (if necessary).
• 🛡️ Security impacts have been considered (if relevant).
• 📖 Documentation updates are complete (if required).
• 🧠 Third-party dependencies and TPIP updated (if required).
