[llvm-objcopy] Add support of symbol modification flags for MachO (ll…
…vm#120895) This patch adds support of the following llvm-objcopy flags for MachO: - `--globalize-symbol`, `--globalize-symbols`, - `--keep-global-symbol`, `-G`, `--keep-global-symbols`, - `--localize-symbol`, `-L`, `--localize-symbols`, - `--skip-symbol`, `--skip-symbols`. Code in `updateAndRemoveSymbols` for MachO is kept similar to its version for ELF. Fixes llvm#120894
