2025-09-10rust: debugfs: Add support for writable filesMatthew Maurer
Extends the `debugfs` API to support creating writable files. This is done via the `Dir::write_only_file` and `Dir::read_write_file` methods, which take a data object that implements the `Reader` trait.

2025-09-10rust: debugfs: Add support for read-only filesMatthew Maurer
Extends the `debugfs` API to support creating read-only files. This is done via the `Dir::read_only_file` method, which takes a data object that implements the `Writer` trait. The file's content is generated by the `Writer` implementation, and the file is automatically removed when the returned `File` handle is dropped.
