[Rust-Axum] Implement support for Basic and Bearer auth in Claims (#20584)

* Implement a custom error handler for unhandled or generic endpoint errors

* Pass in method, host and cookies to error handler

* Update axum to 0.8

* Make API methods take references instead of ownership

* Rebase error handler

* Rebase with updated error handler

* Update deps

* Fix capture group syntax

* Rebase rust-axum-error-handling

* Update docs

* Multipart is also part of the axum update

* Update samples

* Update docs
