perf: avoid multiple calls to runMicrotask (#26378) 
Improves HTTP throughput by 8-9k rps on Linux:

this patch
```
Requests/sec: 145001.69
Transfer/sec:     20.74MB
```

main
```
Requests/sec: 137866.61
Transfer/sec:     19.72MB
```

The improvements comes from the reduced number of calls to
`op_run_microtask` per request. Returning `true` from a macrotask
callback already calls `op_run_microtask` so the extra call was
redundant.

Here's `--strace-ops` output for a single request:

main
```
