This commit shams "performance.markResourceTiming" API by
using a noop function. It is done to provide compatibility with
"npm:undici" package. We should look into actually implementing
this API properly, but I wanted to unblock support for "undici" and
"astro" for now.

Moving some code around in `ext/node` is it's a bit better well defined
and makes it possible for others to embed it.
I expect to see no difference in startup perf with this change.
