[lld] enable fixup chains by default (#79894)

Enable chained fixups in lld when all platform and version criteria are
met. This is an attempt at simplifying the logic used in ld 907:

https://github.com/apple-oss-distributions/ld64/blob/93d74eafc37c0558b4ffb88a8bc15c17bed44a20/src/ld/Options.cpp#L5458-L5549

Some changes were made to simplify the logic:
- only enable chained fixups for macOS from 13.0 to avoid the arch check
- only enable chained fixups for iphonesimulator from 16.0 to avoid the
arch check
- don't enable chained fixups for not specifically listed platforms
- don't enable chained fixups for arm64_32
