[dev.typeparams] cmd/compile: allow embedding Type.Vargen into Sym.Name

Unified IR currently works by hoisting local type definitions to
package scope, which requires giving them a unique name. Its current
solution is to directly embed the ·N suffix in Sym.Name, rather than
set Type.Vargen. This CL extends types/fmt.go to support trimming this
suffix again when appropriate.

Longer term, I want to revisit this hack, but this seemed like the
least invasive solution while also handling generics and local types.
