benchmark: add ipc support to benchmark spawn stdio config
Fix (ipc) in the stdio configuration of the spawn function within the benchmark subsystem.
This PRs fixes the mistake in PR (benchmark: conditionally use spawn with taskset for CPU pinning) where I removed IPC by mistake due to which child.on("message") listener wasn't working.
I also made sure of cpu usage of cores provided to taskset and checked if the csv is all good
