[dev.typeparams] cmd/compile/internal/types2: replace types2.Instantiate with Checker.Instantiate
Allow Checker.Instantiate to work with a nil *Checker receiver
(for now). This opens the door to passing in a *Checker at all
times.
Also, added a verify flag to Instantiate, InstantiateLazy, and
instance, to be able to control if constraint satisfaction should
be checked or not.
Removed types2.Instantiate.
For #47103.
