[dev.typeparams] cmd/compile: change types2.Union API to accept a list of Terms

Browse source 
Instead of providing a list of tildes and types, use a list of
Terms to create a Union, with suitable accessors.

Define the (exported) notion of a Term representing a union term.

This simplified various uses and also will be easier to extend
should we want to add more information to a Term in the future.
