WEBOSLCD13-70662: add enyo.isNonLatinLocale

In order to easily fix WEBOSLCD13-70662, the settings app needs to
be able to make the same latin/non-latin decision about a locale
that the glue code does. To facilitate this, I've isolated the code
into a separate function so that the settings app can call it.
