Test reporter

[Ceres6]

Building on top of #52189

This commit introduces a node:test reporter to the common utils. This reporter can be used to silence output other than errors from node:test. This is useful because in Node's own test suite, the output of node:test is included in the output of the Python test runner.

Refs: #49120

Rebased with main to fix conflicts and added FAIL_FAST envvar.

I kept the failing test so the output can be seen. I will remove it once we agree that output is good enough

[cjihrig]

Personally, this seems fine to me. We can also iterate on it pretty quickly since it's internal only. I'm not sure if I can sign off on this or not since I'm the original author, but throwing my LGTM here.

Also, we'll have to remove that intentional failure before landing.

On a side note, I definitely think we (you?) should open another PR to get rid of the GitHub reporter. It generates far too much output noise.

[Ceres6]

Sure, I can open the PR

[cjihrig]

This is what the output currently looks like:

All of the lines starting with :: will go away once #56468 lands.

@Ceres6 can you remove the intentionally failing test now so that we can progress towards landing this.

[Ceres6]

@cjihrig done!

this will remove all the GitHub annotations (like the ones in the screenshot) on the failed files - is that intended? those seem pretty useful to me

[cjihrig]

@MoLow it is intentional. See #56438 (comment). I pinged you in #52189 (comment) as well.

Is it possible to make the GitHub reporter stop printing to stdout? If it is possible, I'd love to keep the GitHub annotations.

I'l take a look, sure
