Add Mocha/Jest like APIs to node:test

[MoLow]

What is the problem this feature will solve?

help wider adoption of node:test as a native test runner

What is the feature you are proposing to solve the problem?

following the discussion here #40954
it seems like there was no strong opionons against supporting mocha/jest test styles,
So I think adding the describe and it APIs for starters can be fairly easy

What alternatives have you considered?

No response

If this sounds reasonable I would submit a PR

These styles are typically magic globals, which is definitely not a great thing.

If someone wants to import/require describe and it etc, then that'd be one thing.

However, one probably wouldn't want multiple styles in the same codebase. Perhaps it should be configurable, and only one style at a time supported?

I assumed that's what we're talking about (exposing them and not defining them as globals, right?)

Actually I've seen it before (tools like jest typically support both styles and people use them for different things) - I don't do it myself but it definitely exists "in the wild".

@ljharb @benjamingr I was totally thinking something like import { describe, it } from 'node:test', not using globals
