Subject: cmd/cgo: add and use runtime/cgo.Incomplete instead of //go:notinheap

This ports https://go.dev/cl/421879 to libgo. This is a quick port to
update gofrontend to work with the version of cgo in gc mainline.
A more complete port will follow, changing the gc version of cmd/cgo to
choose an approach based on feature testing the gccgo in use.

Updates golang/go#46731

Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/432338
