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.
