WinterCG Minimum Common Web Platform API Alignment

[NathanWalker]

Is your feature request related to a problem? Please describe.

In addition to what the NativeScript runtimes provide, they should also provide all the common interfaces and global objects expected from any state of the art JavaScript runtime. WinterCG is a community group doing excellent work in this space to help runtime interoperability of APIs across runtimes.

@NathanWalker I needed queueMicrotask for the latest Vue Apollo Client to work. I polyfilled it using

import queueMicrotask from "queue-microtask";
global.queueMicrotask ??= queueMicrotask;

which works perfectly. The queue-microtask library is effectively 5 lines of code, so that could be added easily as well.

@NathanWalker I've a question about the polyfills that will be eventually implemented. I see that in the list above there's no mention of Intl API. My main point of interest is the NumberFormat class, as currently to support number formatting via .toLocaleString(), or be to able to use formatToParts(), polyfills have to be used (such as format js polyfills).

Is this something out of scope for this update please?

@dangrima90 Intl will be an optional package you could include when your app needs it vs. being built into runtime by default.
