This eliminates the case in `failed_to_match_macro` to check for a function-like invocation of a macro with no function-like rules. Instead, macro kind mismatches now result in an unresolved macro, and we detect this case in `unresolved_macro_suggestions`, which now carefully distinguishes between a kind mismatch and other errors. This also handles cases of forward-referenced attributes and cyclic attributes. Expand test coverage to include all of these cases.
