  [lld-macho] Move ICF members from InputSection to ConcatInputSection

`icfEqClass` only makes sense on ConcatInputSections since (in contrast
to literal sections) they are deduplicated as an atomic unit.

Similarly, `hasPersonality` and `replacement` don't make sense on
literal sections.

This mirrors LLD-ELF, which stores `icfEqClass` only on non-mergeable
sections.
