Add a new API android.icu.util.LocaleData

1. getDelimiter is useful to avoid quoted text in string resource
and reduce apk size
<string name="verbal_quote_string">“<xliff:g id="value"
example="Mountain">%1$s</xliff:g>”</string>

Two related methods, i.e. setNoSubstitute, getNoSubstitute, are used to
avoid using values in root locale
2. getMeasurementSystem, getPaperSize
Handful method to determine to use km or miles and paper size
