[llvm] [llvm-objdump] Error with relevant message when adding invalid notes (PR #90458)

[James Henderson via llvm-commits]

https://github.com/jh7370 commented:

Please update the PR title/description for the revised behaviour.

Please also update the llvm-objcopy docs and add a release note for the new option.

Finally, please don't force push to active PRs: it makes it difficult to view the difference since the last review (this is why it's against the current LLVM policy). Instead, prefer a merge from main if rebasing is needed.
