[ci-visibility] Remove usage of .asyncResource in mocha plugin

[juan-fernandez]

What does this PR do?

Remove the usage of .asyncResource to check if a function has been wrapped already. Now we'll use another WeakSet wrappedFunctions to check whether the function is wrapped.

I've additionally fixed the plugin tests for mocha, which were not running since the merge of #4314, as seen by this GHA: https://github.com/DataDog/dd-trace-js/actions/runs/9218422124/job/25361943902

It was not running because the instrumentation was split in three files and our test setup didn't allow for that.

After this change, they're running: https://github.com/DataDog/dd-trace-js/actions/runs/9222873007/job/25374958036?pr=4348

Motivation

It's deprecated: nodejs/node#46432

Plugin Checklist

No extra unit tests needed: just check that the ones we have are running and passing.

just a confirmation, you're making the version support lower than it was before (it's usually not a common thing so i'm just pointing it out)

[juan-fernandez]

oh yeah, I should've mentioned this. This file is not there for <8 so this should be a noop. I changed it because the testing matrix became way more complicated. We should probably fix our testing setup but that's for another PR 😄
