cmd/golangorg: add support for module form of Go distributions
Add https://golang.org/toolchain serving appropriate meta tags with mod redirect to https://go.dev/dl/mod. Add https://go.dev/dl/mod/golang.org/toolchain/@v/ redirecting to files in https://dl.google.com/go/. Add https://go.dev/dl/mod/golang.org/toolchain/@v/list listing stable toolchain versions. For golang/go#57001.
