ApiQueryInfo.php: Add code and direction of the page content language

This change introduces two new keys in the response:
* "pagelanguagehtmlcode" for the BCP 47 conform language code
* "pagelanguagedir" for the direction of the language

Example:
 "pagelanguagehtmlcode": "en-GB"
 "pagelanguagedir": "ltr"

The existing key "pagelanguage" contains the internal language code format:
 "pagelanguage": "en-gb"

This duplication avoids reimplementing wfBCP47() and a mapping from
all language codes to the direction of the languages in JavaScript.
