/**
  Allows a program to determine which secondary languages are supported on a given handle for a given primary language

  This routine is intended to be used by drivers to query the interface database for supported languages.
  This routine returns a string of concatenated 3-byte language identifiers, one per string package associated with the handle.

  @param This           A pointer to the EFI_HII_PROTOCOL instance.
  @param Handle         The handle on which the strings reside. Type EFI_HII_HANDLE is defined in EFI_HII_PROTOCOL.NewPack()
                        in the Packages section.
  @param PrimaryLanguage Pointer to a NULL-terminated string containing a single ISO 639-2 language identifier, indicating
                         the primary language.
  @param LanguageString  A string allocated by GetSecondaryLanguages() containing a list of all secondary languages registered
                         on the handle. The routine will not return the three-spaces language identifier used in other functions
                         to indicate non-language-specific strings, nor will it return the primary language. This function succeeds
                         but returns a NULL LanguageString if there are no secondary languages associated with the input Handle and
                         PrimaryLanguage pair. Type EFI_STRING is defined in String.

  @retval EFI_SUCCESS            LanguageString was correctly returned.
  @retval EFI_INVALID_PARAMETER  The Handle was unknown.
