Add micro-benchmarks that isolate the hot paths targeted by the
JavaScript-to-C++ migration of child_process:
- child-process-spawn-options.js scales the env vars and args that
ProcessWrap::Spawn must marshal across the JS/C++ boundary.
- child-process-ipc-roundtrip.js measures IPC throughput for both the
json and advanced serializers across a range of payload sizes.
- child-process-exec-maxbuffer.js measures stdout accumulation and
maxBuffer handling in execFile().
These establish the baseline that later migration PRs are compared
against. There is no runtime behavior change.
