  [lld-macho] Remove partially supported 32-bit ARM arch

We never really supported 32-bit ARM arch entirely, and partial support was added for
very specific features. Regardless, it fails to even link the most basic applications that at
this point, it might be better to move this arch as unsupported. Given that Apple will be
moving towards arm64 long term, I don't see any reason for anyone to invest time in
supporting this either, and for those who still need it should use apple's ld64 linker.

Fixes #62691
