Alex Rønne Petersen f87b443af1 link.MachO: Add support for the -x flag (discard local symbols).
This can also be extended to ELF later as it means roughly the same thing there.

This addresses the main issue in #21721 but as I don't have a macOS machine to
do further testing on, I can't confirm whether zig cc is able to pass the entire
cgo test suite after this commit. It can, however, cross-compile a basic program
that uses cgo to x86_64-macos-none which previously failed due to lack of -x
support. Unlike previously, the resulting symbol table does not contain local
symbols (such as C static functions).

I believe this satisfies the related donor bounty: https://ziglang.org/news/second-donor-bounty
