[Applications.Common] Add Globalization invariant mode check (#3998)

In globalization-invariant mode, creating a new CultureInfo() throws
a CultureNotFoundException exception. If the process runs in invariant
mode, the CoreApplication doesn't set CultureInfos. And, the
CultureInfoHelper uses ToLowerInvaraint() instead of ToLower() with CultureInfo("en-US");
