Subject: [PATCH] fix(perf): enable compile cache if present (#7901)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adding support to
[module.enableCompileCache](https://nodejs.org/docs/v22.11.0/api/module.html#moduleenablecompilecachecachedir),
added by https://github.com/nodejs/node/pull/54501, Typescript got [2.5x
perf on
tsc](https://devblogs.microsoft.com/typescript/announcing-typescript-5-7-beta/#support-for-v8-compile-caching-in-node.js).

On my machine, for the command `--version`, I got the following results:

```bash
Benchmark 1: node bin/npm-cli.js --version
  Time (mean ± σ):      58.0 ms ±   1.1 ms    [User: 51.8 ms, System: 16.8 ms]
  Range (min … max):    56.5 ms …  62.6 ms    51 runs

Benchmark 2: node bin/npm-cli-with-cache.js --version
  Time (mean ± σ):      52.9 ms ±   1.0 ms    [User: 46.5 ms, System: 16.8 ms]
  Range (min … max):    51.4 ms …  55.5 ms    56 runs

Summary
  'node bin/npm-cli-with-cache.js --version' ran
    1.10 ± 0.03 times faster than 'node bin/npm-cli.js --version'
```

I run the same test with `npm run empty` and I got the same 10%
improvement.
