[TIMOB-27892] Android: Update toLocale*String() methods to support locale/options

*Summary:* On Android, the following methods ignore the locales and options arguments. They also ignore the current locale and always use "en-US" when formatting a string. * [Date.toLocaleString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleString) * [Date.toLocaleDateString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleDateString) * [Date.toLocaleTimeString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleTimeString) * [Number.toLocaleString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/toLocaleString) * [String.localeCompare()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/localeCompare) * [String.toLocaleLowerCase()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/toLocaleLowerCase) * [String.toLocaleUpperCase()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/toLocaleLowerCase) On iOS, the above methods *+do+* support locale/options. We should add the same on Android for parity and to better support the standard JavaScript APIs. *Note:* To add official Intl support to V8, we would have to #if it in, but this involves adding the ICU (International Components for Unicode) C++ library which is about 20 MB per architecture. This is too big and is not mobile friendly. Especially since Google Play has a 100 MB limit on APKs. So, the most reasonable solution is to implement this ourselves in Java. *Alternatives:* On older Titanium versions, your only option to generate localized strings was via APIs: * [String.formatDecimal()](https://docs.appcelerator.com/platform/latest/#!/api/Global.String-method-formatDecimal) * [String.formatDate()](https://docs.appcelerator.com/platform/latest/#!/api/Global.String-method-formatDate) * [String.formatTime()](https://docs.appcelerator.com/platform/latest/#!/api/Global.String-method-formatTime)
