* Improve `debug_handler` to use the correct span for specific bounds
This results in better localised error messages, as they now point
directly to the corresponding argument instead of to the macro itself.
* Improve some error messages behind a `nightly-error-messages` feature
flag
This uses the nightly only `rustc_on_unimplemented` attribute to improve
some error messages when users try to use invalid handler functions.
This should be seen as prove of concept, not as full solution for all
potential error cases.
The underlying feature is currently marked as permanently unstable, but
I'm working on getting this specific attribute (or an attribute with
different name, similar functionality) ready to work on a stable compiler.
* Apply suggestions from code review

* Enable the `nightly-error-messages` feature unconditionally for nightly compilers
* Use a nightly compiler to run the axum-marcos compile fail tests
* update to newer nightly
* Run axum-macros tests on nightly
* tweak compile error hints a bit
* more tweaks
* update test

Previously
```rust
handler.layer(RequestBodyLimitLayer::new(...)).with_state(...)
```
didn't work because we required the same request body all the way
through.
* Change `FailedToDeserializeQueryString` rejection for `Form`
Its now called `FailedToDeserializeForm`.
* changelog
* Make dedicate rejection type for axum-extra's `Form`
* update trybuild test
* Make dedicate rejection type for axum-extra's `Query`
* Add RawForm extractor
* Change RawForm(String) to RawForm(Option<String>)
* Fix tests
* Use Bytes instead of Option<String> and add tests
* Add test for empty body
* Update CHANGELOG
* small docs tweaks
* changelog nit

* add `#[derive(FromRef)]`
* tests
* don't support skipping fields
probably wouldn't work at all since the whole state likely needs `Clone`
* UI tests
* changelog
* changelog link
* revert hello-world example, used for testing
* Re-export `#[derive(FromRef)]`
* Don't need to return `Result`
* use `collect` instead of quoting the iterator
* Mention it in axum's changelog
* Add a dedicated error message for state type inference issues
* Generate valid code even if state type can't be inferred
* Also error on state type inference for debug_handler
