let proc-macro's provide a formatting hook for rustfmt #5656

I'm building an app based on dioxus that uses the rsx! proc macro extensively. it's basically html with embedded rust closures. the rsx! macro even has an autoformatter [0] used by a vscode plugin. Since we can't run that in ci it would be really nice if we could somehow tell rustfmt how to format the code.
