Follow-up to #6721. Reduce SHParseDisplayName failures. JIRA issue: CORE-19495 - Re-implement CFSFolder::ParseDisplayName method to validate the names. - Add CFSFolder::_ParseSimple, CFSFolder::_GetFindDataFromName, and CFSFolder::_CreateIDListFromName helper methods. - Add PathIsDotOrDotDotW, PathIsValidElement, PathIsDosDevice, and SHILAppend helper functions. - Delete GetNextElementW and add Shell_NextElement function.
