[Object] Extend MachOUniversalBinary::getObjectForArch

Make the method MachOUniversalBinary::getObjectForArch return MachOUniversalBinary::ObjectForArch
and add helper methods MachOUniversalBinary::getMachOObjectForArch, MachOUniversalBinary::getArchiveForArch
for those who explicitly expect to get a MachOObjectFile or an Archive.
