Keith Randall 3081f817da cmd/compile: always remove receiver type from instantiated method values
If a type T has a method foo, then

var t T
var i interface{} = t.foo

The type of foo is a method type, but the type of t.foo should be a
standard function type. Make sure we always do that conversion.

Fixes #47775
