Implement queueMicrotask()
Description
I've just implemented a custom renderer to GTK for SolidJS. It works pretty well, except the function createResource, which calls queueMicrotask, a function that isn't implemented in gjs.
MDN documentation: https://developer.mozilla.org/en-US/docs/Web/API/queueMicrotask.
Probably this could be implemented as a polyfill, but since it's a function "similar" to setTimeout and setInterval, I believe this should be implemented directly in gjs.
