This PR depends on #12015 and #12016 being merged first. However, a few changes in 52cb7df first must be backported to #12016.

This PR introduces error codes for all constraints with multiple error paths. This lets you determine what exactly the reason was that a constraint failed:

```php
$validator = Validation::createValidator();

$violations = $validator->validate('0-4X19-92619812', new Isbn());

foreach ($violations as $violation) {
    var_dump($violation->getCode());
    // => int(3)
    var_dump(Isbn::getErrorName($violation->getCode()));
    // => string(24) "ERROR_INVALID_CHARACTERS"
    var_dump($violation->getConstraint()->getErrorName($violation->getCode()));
    // => string(24) "ERROR_INVALID_CHARACTERS"
}
```

The `getErrorName()` method is especially helpful for REST APIs, where you can return both an error code and a description of that error now.

**Todos**

- [x] Backport a few structural changes to #12016
- [x] Update constraints outside of the Validator component
- [x] Rebase on master (after merging #12015 and #12016)
given that it extends the File constraint, it should not reuse the values already used in File to avoid clashes leading to ambiguity (the ImagineValidator calls the parent validation)
