ImmutableEnumChecker on a list coming from List.of(...) which is immutable

### Description of the problem / feature request:

I'm getting `ImmutableEnumChecker` errors on such enum:

```
public enum SomeEnum {

SOME_VALUE(List.of(TYPE_1, TYPE_2))

public final List types;

SomeEnum(List types) {
this.types = types;
}
}
```

ErrorProne should not trigger `ImmutableEnumChecker` on collections created from `ImmutableCollections`
