  -----------
  Reapply "[llvm-objcopy][ELF] Add an option to remove notes (#118739)"

This fixes "unused-local-typedef" warnings in 9324e6a7a5.

This adds an option `--remove-note=[name/]type` to selectively delete
notes in ELF files, where `type` is the numeric value of the note type
and `name` is the name of the originator. The name can be omitted, in
which case all notes of the specified type will be removed. For now,
only `SHT_NOTE` sections that are not associated with segments are
handled. The implementation can be extended later as needed.
