As discussed around #3792, identify the import a diagnostic message came from prior to the diagnostic message itself. This occurs during location translation so that the logic can be central. I'd considered associating the parse node with ImportRef instructions, but I realized about halfway through that because I need to store the ImportDirectiveId on the ImportIR for cross-package imports, it's there for use in location translation without extra work. That saves a fair amount of stringing it through declarations, as well as an oddity where ImportRef instructions would have a node that didn't really represent them.
