codify "platform" into resolution logic, server-fn/fullstack overhaul (#4596)

overhaul dioxus fullstack using a new implementation of server_fn

This PR is a complete rewrite of dioxus fullstack designed to improve compatibility with axum and to fix a number of compilation errors based on feature flag unification plumbing through macros.

//! Calculator
//!
//! This example is a simple iOS-style calculator. Instead of wrapping the state in a single struct like the
//! `calculate_mutable` example, this example uses several closures to manage actions with the state. Most
//! components will start like this since it's the quickest way to start adding state to your app. The `Signal` type
//! in Dioxus is `Copy` - meaning you don't need to clone it to use it in a closure.
//!
//! Notice how our logic is consolidated into just a few callbacks instead of a single struct. This is a rather organic
//! way to start building state management in Dioxus, and it's a great way to start.

//! This example showcases a simple calculator using an approach to state management where the state is composed of only

//!
//! Generally, you'll want to split your state into several signals if you have a large application, but for small

//! Tiny CRM - A simple CRM app using the Router component and global signals
//!
//! This shows how to use the `Router` component to manage different views in your app. It also shows how to use global
//! signals to manage state across the entire app.
//!
//! We could simply pass the state as a prop to each component, but this is a good example of how to use global state
//! in a way that works across pages.
//!
//! We implement a number of important details here too, like focusing inputs, handling form submits, navigating the router,
//! platform-specific configuration, and importing 3rd party CSS libraries.

# Dioxus Example: An e-commerce site using the FakeStoreAPI
This example app is a fullstack web application leveraging the [FakeStoreAPI](https://fakestoreapi.com) and [Tailwind CSS](https://tailwindcss.com/).
![Demo Image](demo.png)
# Development
1. Run the following commands to serve the application:
```bash
dx serve
```
Note that in Dioxus 0.7, the Tailwind watcher is initialized automatically if a `tailwind.css` file is find in your app's root.
# Status
This is a work in progress. The following features are currently implemented:
- [x] A homepage with a list of products dynamically fetched from the FakeStoreAPI (rendered using SSR)
- [x] A product detail page with details about a product (rendered using LiveView)
- [ ] A cart page
- [ ] A checkout page
- [ ] A login page

//! The simplest example of a Dioxus app.
//!
//! In this example we:
//! - import a number of important items from the prelude (launch, Element, rsx, div, etc.)
//! - define a main function that calls the launch function with our app function
//! - define an app function that returns a div element with the text "Hello, world!"
//!
//! The `launch` function is the entry point for all Dioxus apps. It takes a function that returns an Element. This function
//! calls "launch" on the currently-configured renderer you have. So if the `web` feature is enabled, it will launch a web
//! app, and if the `desktop` feature is enabled, it will launch a desktop app.
