Some fixes for JDWP with the interpreter.

- GetStackDepth checks if the thread is suspended, unless the thread is
  itself.
- Scoped the breakpoints lock during UpdateDebugger to prevent it being
  held during PostLocationEvent.
- Removed locking of breakpoints lock in DebugCallbackContext since it's
  already holding it.
- Added level for breakpoints lock to prevent lock level violations.
