Pull Request Overview

Refactors stack trace handling by moving request/response tracking from CpuStates into GDBTargetDebugTracker and introducing a consolidated SessionStackTrace event.

• Introduces SessionStackTrace interface and replaces separate request/response events with a single onStackTrace event.
• Migrates stack trace request bookkeeping from CpuStates to GDBTargetDebugTracker.
• Simplifies CpuStates by removing per-session stack trace maps and updating handler logic.
