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.
