fix(node/perf_hooks): stub eventLoopUtilization (#24501)

Browse source 
This PR stubs `perf_hooks.eventLoopUtilization` to make the tests of
[hapi](https://github.com/hapijs/hapi) start. Previously, they'd all
error because of this function throwing a not implemented error. This
brings down the test failures in their suite from 982 to 68 failures.
