samples: add first Rust examples The beginning of a set of Rust modules that showcase how Rust modules look like and how to use the abstracted kernel features. It also includes an example of a Rust host program with several modules. These samples also double as tests in the CI.

samples: rust: Add debugfs sample driver Adds a new sample driver that demonstrates the debugfs APIs. The driver creates a directory in debugfs and populates it with a few files: - A read-only file that displays a fwnode property. - A read-write file that exposes an atomic counter. - A read-write file that exposes a custom struct. This sample serves as a basic example of how to use the `debugfs::Dir` and `debugfs::File` APIs to create and manage debugfs entries.

samples: rust: Add scoped debugfs sample driver Adds a new sample driver `rust_scoped_debugfs` that demonstrates the use of the scoped debugfs APIs. The driver creates a `control` directory with two write-only files, `create` and `remove`. Writing a name and a series of numbers to `create` will create a new subdirectory under a `dynamic` directory. This new subdirectory will contain files that expose the numbers as atomic values. Writing a name to `remove` will remove the corresponding subdirectory from the `dynamic` directory. This sample serves as an example of how to use the `debugfs::Scope` and `debugfs::ScopedDir` APIs to create and manage debugfs entries that are tied to the lifetime of a data structure.

Revert "USB: disable rust bindings from the build for now" This reverts commit c584a1c7c8a192c13637bc51c7b63a9f15fe6474. It brings the rust bindings for USB back into the build so that we can work off of this for future kernel releases.

rust/kernel: Add faux device bindings This introduces a module for working with faux devices in rust, along with adding sample code to show how the API is used. Unlike other types of devices, we don't provide any hooks for device probe/removal - since these are optional for the faux API and are unnecessary in rust.
