Jez Ng 6c9f681252 [lld-macho] Support EH frame pointer encodings that use sdata4 ...

Previously we only supporting using the system pointer size (aka the
`absptr` encoding) because `llvm-mc`'s CFI directives always generate EH
frames with that encoding. But libffi uses 4-byte-encoded, hand-rolled
EH frames, so this patch adds support for it.

Fixes #56576.
