Reapply "[lld] enable fixup chains by default (#79894)" (#99255)

This reverts commit f55b79f59a77b4be586d649e9ced9f8667265011.

The known issues with chained fixups have been addressed by #98913,
#98305, #97156 and #95171.

Compared to the original commit, support for xrOS (which postdates
chained fixups' introduction) was added and an unnecessary test change
was removed.

----------
Original commit message:

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
