Returns the identifier for the language code of the given `Locale`.

This method checks for the availability of specific APIs introduced in iOS 16.0 and macOS 13.0 versions or later. If these APIs are available, it returns the `identifier` property of the `languageCode` from the `Locale`. Otherwise, it uses the `languageCode` property directly from the `Locale`.

- Parameter locale: The `Locale` for which the language code identifier is required.

- Returns: The language code identifier of the given `Locale`. If the specific APIs are unavailable (i.e., the device's OS version is older than iOS 16.0 or macOS 13.0), it returns the language code directly.
