[Multi-language] : Create endpoints to feed the Multi-language Component for the Edit Contentlet sidebar

User Story

As a dotCMS User, I want to view locale-related information of the Contentlet that I'm creating or editing.

Acceptance Criteria

Expose the required data via REST:

An Endpoint that takes a Contentlet Identifier which returns ALL languages in the dotCMS repo. For each of them, a new attribute will indicate whether the Contentlet is available in such a language or not.
An Endpoint that returns the currently selected default Language.

The data structure will be the same one used by the soon-to-be-deprecated method in the PageResource class. For instance:

{
"entity": [
    {
        "country": "United States",
        "countryCode": "US",
        "id": 1,
        "isoCode": "en-us",
        "language": "English",
        "languageCode": "en",
        "translated": true
    },
    {
        "country": "Espana",
        "countryCode": "ES",
        "id": 2,
        "isoCode": "es-es",
        "language": "Espanol",
        "languageCode": "es",
        "translated": false
    }
],
"errors": [],
"i18nMessagesMap": {},
"messages": [],
"pagination": null,
"permissions": []
}
