BinUtils: Avoid llvm-strip on Apple platforms
Since commit cf82300a63 (BinUtils: Clarify search logic and make it more
consistent, 2021-05-27, v3.21.0-rc1~119^2~2) we prefer `llvm-strip` over
`strip` when using Clang. However, `llvm-strip` seems to produce
unusable binaries in cases involving chained fixups. Prefer Apple's
`strip` over `llvm-strip` on `APPLE` platforms.
We still need to consider `llvm-strip` as a fallback as explained for
`llvm-ar` by commit fee36b7a78 (BinUtils: Restore llvm-ar fallback on
Apple platforms, 2022-03-15, v3.23.0-rc4~12^2).
Issue: #24601
