bug: (go1.27) unusedmethod analyzer false positive with generic methods

[ldez]

go1.27 will introduce generic methods.

unusedmethod analyzer is not working as expected with those new elements.

main.go

package main

func main() {
	var g G[string]
	var _ I = g

	g.m("foo")

	var h H
	h.m[string]("foo")
}

type G[P any] struct{}

func (G[P]) m(P) {}

type I interface {
	m(string)
}

type H struct{}

func (H) m[P any](P) {}
