[dev.typeparams] cmd/compile/internal/types2: remove Named.SetTArgs

Calling SetTArgs without substituting can leave the type in incoherent
state, so we should avoid exposing this API unless necessary. Since it
is currently not used by the importer(s), it is probably not necessary
to expose for 1.18, so remove it.
