ld64 can emit dylibs that support more than one platform (typically macOS and
macCatalyst). This diff allows LLD to read in those dylibs. Note that this is a
super bare-bones implementation -- in particular, I haven't added support for
LLD to emit those multi-platform dylibs, nor have I added a variety of
validation checks that ld64 does. Until we have a use-case for emitting zippered
dylibs, I think this is good enough.
