refactor(cli): move op sanitizer to Rust (#22413)

The format of the sanitizers will change a little bit:

- If multiple async ops leak and traces are on, we repeat the async op
header once per stack trace.
- All leaks are aggregated under a "Leaks detected:" banner as the new
timers are eventually going to be added, and these are neither ops nor
resources.
 - `1 async op` is now `An async op`
- If ops and resources leak, we show both (rather than op leaks masking
resources)
