[lld/mac] Don't crash when dead-stripping removes all unwind info
If the input has compact unwind info but all of it is removed
after dead stripping, we would crash. Now we don't write any
__unwind_info section at all, like ld64.
This is a bit awkward to implement because we only know the final
state of unwind info after UnwindInfoSectionImpl<Ptr>::finalize(),
which is called after sections are added. So add a small amount of
bookkeeping to relocateCompactUnwind() instead (which runs earlier)
so that we can predict what finalize() will do before it runs.
Fixes PR51010.
