Compile the Intl data by invoking a single command, and make it work out-of-the-box. (Split from #28831)

```bash
$ src/Symfony/Component/Intl/Resources/bin/compile
```

run in repository root because of

https://github.com/symfony/symfony/blob/b7e798ef745a09ca2e76fba4afad0a04fcbd9195/src/Symfony/Component/Intl/Data/Generator/LocaleDataGenerator.php#L141

3.4 is ok, 4.2 is not because of #28833 but new locales are introduced in https://github.com/symfony/symfony/pull/28977/files#diff-f52da32e1ee6b93598814090d0749aa6R1

So as long as 3.4 is supported, but branches above add filters etc. during generation we're risking this discrepancy. I suggest after merge in upper branches to re-run `compile` (potential for automating, but run if needed :))

Related to #30584 , the tests we're missing updated fixtures. My bad also 😅

The intl docker image comes with build-essential packages now, so there's no need for additional installation steps.
