Add display names for languages and regions for Android

DisplayNames API in ECMA 402 [1] was not fully supported in v8 on Android
because language and region names were excluded in the ICU data
file for Android to save the download size.

Now that Android Chrome is not under the size pressure any more [2],
add back language and region names.
