  [lld-macho][nfc] Convert the mock libSystem.tbd to TBDv4

It doesn't seem like TBDv3 allows for specifying multiple platforms, so I'm
upgrading us to TBDv4. (We need to support multiple platforms in order to test
that we can handle zippered dylibs; that functionality will be added in an
upcoming diff.)

  [lld-macho] Support loading of zippered dylibs

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.

Fixes PR49597.
