feat: add v8-compile-cache

[vankop]

Which issue, if any, is this issue related to?

inspired by eslint/eslint#11921 =)

Is there anything in the PR that needs further explanation?

nothing

It would be good to get some before and after benchmarks (like so), so we know the benefit of this change.

[vankop]

Don't now how it works exactly =)
For me

time node -e "require('./bin/stylelint')"

after several runs 0.2s

For code in master after several runs 0.23s
For latest npm package 0.3s

[alexander-akait]

Try to run stylelint multiple times with multiple require and without

[vankop]

@evilebottnawi something like that

function measureRequire() {
  const t = process.hrtime();
  require("./bin/stylelint");
  console.log('stylelint: ' + process.hrtime(t)[1] / 1e+6);
}

const retry = fn => times => new Array(times).fill(0).forEach((_, i) => fn(i));

retry(measureRequire)(10);

???

Are those the results from the PR branch or master?

[alexander-akait]

@vankop just create suite WITH_CACHE (where true) and WITH_CACHE (where unspecific)

[vankop]

Sorry, did not understand at the beginning that I need to require code without v8-compile-cache

Are those the results from the PR branch or master?

Master branch

[alexander-akait]

Good perf on first run

[jeddy3]

Yep, better on first run. LGTM.
