[llvm] [doc] Add missing info for multiply specifiable objcopy opts (PR #111153)

[via llvm-commits]

https://github.com/bd1976bris created https://github.com/llvm/llvm-project/pull/111153

Some objcopy options can usefully be specified multiple times. The text for most of the options where this is true explicitly note this. Add this info to the text for the options which don't currently explicitly note this.
