[llvm-objdump] Start on -chained_fixups for llvm-otool
And --chained-fixups for llvm-objdump.
For now, this only prints the dyld_chained_fixups_header and adds
plumbing for the flag. This will be expanded in future commits.
When Apple's effort to upstream their chained fixups code continues,
we'll replace this code with the then-upstreamed code. But we need
something in the meantime for testing ld64.lld's chained fixups
code.
Update chained-fixups.yaml with a file that actually contains
the chained fixup data (`LinkEditData` doesn't encode it yet,
so use `__LINKEDIT` via `--raw-segment=data`).
