Ordinal prebuilt entity for a LUIS app

[!INCLUDE deprecation notice]

Ordinal number is a numeric representation of an object inside a set: first, second, third. Because this entity is already trained, you do not need to add example utterances containing ordinal to the application intents. Ordinal entity is supported in many cultures.
