Change the names of cluster-objects function arguments. (#27945)

Using "tag" as a function argument leads to compile failure when a struct with a
field named "Tag" (which becomes a member named "tag") is added to the spec.
Change to aTag (and aWriter) to avoid the name collision.

This does not change either API or ABI for consumers; just the naming of the
argument inside the function.
