There are no IN MAME functions or commands to silence any of those messages. You'd need to edit the source and remove/comment the areas where the dialogs are and compile yourself a new binary. I cannot see that being all that useful, especially if your save state fails to load or save for whatever reasons which can happen from version to version.
