switch to tap for ci/core/tracing/profiling tests

[rochdev]

What does this PR do?

Update some tests to run in isolated workers using tap. There is also no global setup anymore, so individual tests files can be run directly with node somefile.spec.js.

Motivation

We need a way to isolate tests so that we can write integration tests without complex logic to cleanup after the suite, which is also not always possible.

Additional Notes

This is exactly the same code as #2538 but without AppSec as there are new test failures that I wasn't able to fix. I also wasn't able to merge properly as there were too many changes on the main branch, so I decided to open a new PR, but again it's the same code as #2538 so any review that was done there applies here as well.

@tlhunter For the comment in #2538 (comment): datadog-core has its own setup file, so that's the file that requires ../setup/tap.

@bengl For the comment in #2538 (comment) it was fixed a long time ago.

@juan-fernandez Please confirm if moving to tap works for you, if not I can just remove CI from the PR, although this should enable you to run tests in isolation without having to rely on the integration tests.

@simon-id I removed AppSec since it was failing, but I still moved it to its own jobs, so you can decide to switch to tap as well after this PR is merged or keep Mocha for your team.

[juan-fernandez]

LGTM from CI Vis' perspective. I only worry about a test we're skipping. Just to confirm: this PR is a noop for plugins test, right?

Correct, at least for now.
