Please review this small fix to update pipe mode for attach operation communication. - `FILE_FLAG_FIRST_PIPE_INSTANCE`: there is "retry" logic if pipe creation failed [1], with this flag `CreateNamedPipe` fails when pipe with the same name already exists; - `PIPE_REJECT_REMOTE_CLIENTS`: attach works only for local processes, the flag adds extra protection from remote connections.
