* 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

Previously
```rust
handler.layer(RequestBodyLimitLayer::new(...)).with_state(...)
```
didn't work because we required the same request body all the way
through.
