Node.js has added a built-in compile cache so this PR changes the code to prefer that over v8-compile-cache.

https://nodejs.org/docs/v22.11.0/api/module.html#moduleenablecompilecachecachedir

Fixes #342
Closes #573 (supersedes it)

nit: we can minimize the diff, to avoid cluttering git blame

It would always affect npm as it has to check the version first.

Yeah that's what I'm saying, and if native support is indeed disabled – otherwise it would have to do the check anyway
