Add "hasEnumEntries" flag to class metadata

With this flag we can distinguish enum classes that have `entries`
property in the compiled bytecode (see `LanguageFeature.EnumEntries`).
This is needed to be able to understand in the frontend whether
`entries` can be called for that class. For Native and JS, this is
currently not possible even if the feature is enabled, but the class
was compiled with disabled feature.
