rust: debugfs: support blobs from smart pointers

Extend Rust debugfs binary support to allow exposing data stored in
common smart pointers and heap-allocated collections.

- Implement BinaryWriter for Box<T>, Pin<Box<T>>, Arc<T>, and Vec<T>.
- Introduce BinaryReaderMut for mutable binary access with outer locks.
- Implement BinaryReaderMut for Box<T>, Vec<T>, and base types.
- Update BinaryReader to delegate to BinaryReaderMut for Mutex<T>,
  Box<T>, Pin<Box<T>> and Arc<T>.

This enables debugfs files to directly expose or update data stored
inside heap-allocated, reference-counted, or lock-protected containers
without manual dereferencing or locking.
