…IMIZED in vectorcall fast path

…_cleanup frames, guard trace dispatch

- Extract datastack_frame_size_bytes_for_code as free function, use it
  to compute init_cleanup stack bytes instead of hardcoded constant
- Add monitoring_disabled_for_code to skip instrumentation for
  synthetic init_cleanup code object in RESUME and execute_instrumented
- Add is_trace_event guard so profile-only events skip trace_func dispatch
- Reformat core.rs (rustfmt)
