test: test-crypto-keygen.js should be split into multiple tests to avoid timeout in CI

[joyeecheung]

It looks like #41206 is coming back to the CI, see https://ci.nodejs.org/job/node-test-binary-windows-js-suites/22596/RUN_SUBSET=2,nodes=win2012r2-COMPILED_BY-vs2019-x86/testReport/junit/(root)/parallel/test_crypto_keygen_/ It's a test with 1800+ lines that is crammed with computation-intensive crypto tests that seem to be logically separable. On my local machine which is quite powerful it still takes >5s to run. It would be good to split it into multiple tests to avoid timing out in the CI (I could do it if no one picks this up, but I feel like maybe people from @nodejs/crypto have better ideas about how to split them properly and give the split tests proper names - if I am doing it I would probably just name them test-crypto-keygen-1.js, test-crypto-keygen-2.js..)

If I want to reproduce it, can I run it with the command below?

python.exe tools/test.py -J --repeat=1000 test/parallel/test-crypto-keygen.js

You can just run it with out/Release/node test/parallel/test-crypto-keygen.js and see how long it takes and try to split it to make the split tests run faster, the time out only reproduces on very slow machines, running it many times would not make a difference if you run it on a fast machine.

And test-crypto-dh.js too (which crams 19 crypto.createDiffieHellman() calls in one test

I am going to do it to deflake the CI sooner than later.

I was checking to give it a try, but you've already fixed it. That's a good job. 👍

Here is a list of crypto tests that took more than 1s for me locally (probably would be much slower in the CI on slow machines, in the failures referenced above, over 2 minutes)
