Add missing alias targets for C++ util libraries (#15783)

Until recently, these targets were dependencies of `//:protobuf` and could thus
be accessed through that target. But now that we are adhering to the layering
check, we need to provide proper access in a way that respects that check. This
change uses top-level alias targets following the existing pattern.
