Support State with #[derive(FromRequest[Parts])] (#1391) 
* Support `State` with `#[derive(FromRequest[Parts])]`

Fixes https://github.com/tokio-rs/axum/issues/1314

This makes it possible to extract things via `State` in
`#[derive(FromRequet)]`:

```rust
struct Foo {
    state: State<AppState>,
}
```

The state can also be inferred in a lot of cases so you only need to
write:

```rust
struct Foo {
    // since we're using `State<AppState>` we know the state has to be
    // `AppState`
    state: State<AppState>,
}
```

Same for

```rust
struct Foo {
    #[from_request(via(State))]
    state: AppState,
}
```

And

```rust
struct AppState {}
```

I think I've covered all the edge cases but there are (unsurprisingly) a
few.

* make sure things can be combined with other extractors

* main functions in ui tests don't need to be async

* Add test for multiple identicaly state types

* Add failing test for multiple states
