Subject: [PATCH] benchmark: add ipc support to spawn stdio config

Enabled inter-process communication (ipc) in the stdio configuration
of the spawn function within the benchmark subsystem.
This change allows for improved data exchange between parent
and benchmarked child processes, addressing limitations in performance
testing scenarios.

Fixes: https://github.com/nodejs/node/issues/52233
