This function adds the string String to the group of strings owned by PackageList, with the
specified font information StringFontInfo, and returns a new string id.
The new string identifier is guaranteed to be unique within the package list.
That new string identifier is reserved for all languages in the package list.
@param This A pointer to the EFI_HII_STRING_PROTOCOL instance.
@param PackageList The handle of the package list where this string will
be added.
@param StringId On return, contains the new strings id, which is
unique within PackageList.
@param Language Points to the language for the new string.
@param LanguageName Points to the printable language name to associate
with the passed in Language field.If LanguageName
is not NULL and the string package header's
LanguageName associated with a given Language is
not zero, the LanguageName being passed in will
be ignored.
@param String Points to the new null-terminated string.
@param StringFontInfo Points to the new string's font information or
NULL if the string should have the default system
font, size and style.
@retval EFI_SUCCESS The new string was added successfully.
@retval EFI_NOT_FOUND The specified PackageList could not be found in

@retval EFI_OUT_OF_RESOURCES Could not add the string due to lack of resources.
@retval EFI_INVALID_PARAMETER String is NULL, or StringId is NULL, or Language is NULL.

current database.
