[dev.regabi] cmd/compile: add ssa.Aux tag interface for Value.Aux

It's currently hard to automate refactorings around the Value.Aux
field, because we don't have any static typing information for it.
Adding a tag interface will make subsequent CLs easier and safer.

Passes buildall w/ toolstash -cmp.

Updates #42982.
