Fix OOM issue in processRegistryUpdates

[dapplion]

Motivation

WeakRef keeps a strong reference to its constructor value until the event loop ticks. Without this sleep(0) all the SubTree(s) created updating the validators registry won't be garabage collected causing an OOM crash. Tracking issue nodejs/node#39902

Description

Yield to the event loop on every benchmark fn() run
