Looks like #124936 was reverted (for modifying JSON output), but the test for JSON output with errors was deleted in #126587 (to attempt to fix failing build)
This will add back a test and a new one for llvm-dwarfdump to validate the JSON for errors. One case where the sub-categories will eventually appear and another where not.
test plan:
