Now that ld64.lld points to the new Darwin backend, we can pass it the newer
`-platform_version` flag.

Most of the changes were originally in D95204: [lld-macho] Switch default to new Darwin backend <https://reviews.llvm.org/D95204>, but I backed them out due to
test failures on builds which have `CLANG_DEFAULT_LINKER=lld`. The tests are
properly updated in this diff. @thakis, want to have a second look to make sure
things make sense? I haven't worked with clang-driver code much.
