Currently the codes are only exposed in aggregated form, i.e. through
name(), bcp47Name(). There are use cases though where you are only
interested in either language, country, or script codes. One example
is in Qt Linguist.
This patch therefore exposes the static languageToCode(),
countryToCode(), scriptToCode() methods that were so far only available
in the private API also in the public API.
[ChangeLog][QtCore][QLocale] Added static languageToCode(),
countryToCode() scriptToCode() methods that convert enum values
to the respective ISO code strings.
