Add coverage for Promise.any proposal

[chicoxyzzy]

This issue is to track the progress of the test262 coverage of the stage 3 Promise.any proposal. https://github.com/tc39/proposal-promise-any. Tests also should cover AggregateError. (covered by #2406)

I'm starting to work on this.

Oh, I didn't notice #2406 by @leobalter

Hi @chicoxyzzy, how is the progress on the tests for Promise.any? I have time available this week for it if you haven't started yet. Please, let me know!

[chicoxyzzy]

Hi Leo! I have asked you the same question on #tc39 IRC channel couple hours before 😀 I will work on adding Promise.any to JSC soon, so I will need test262 tests. I didn't start yet, so you can take it or leave it to me (I was going to start working on tests tomorrow). Either way works for me 🙂

[leobalter]

It’s very nice if you wanna write the tests. I’ll focus on other features currently on Stage 3. I’m looking forward to review the tests.

Coverage for AggregateError should be done.

@leobalter awesome, thank you! I've started to work on Promise.any tests (using #2124 as a reference)

#2533 is merged now, so I'll close this issue. Thank you @rwaldron! 👏
