rust: error: `impl Debug` for `Error` with `errname()` integration
Integrate the `Error` type with `errname()` by providing a new `name()` method. Then, implement `Debug` for the type using the new method. [ Miguel: under `CONFIG_SYMBOLIC_ERRNAME=n`, `errname()` is a `static inline`, so added a helper to support that case, like we had in the `rust` branch. Also moved `#include` up and reworded commit message for clarity. ] Co-developed-by: Wedson Almeida Filho <walmeida@microsoft.com> Signed-off-by: Wedson Almeida Filho <walmeida@microsoft.com> Co-developed-by: Sven Van Asbroeck <thesven73@gmail.com> Signed-off-by: Sven Van Asbroeck <thesven73@gmail.com> Signed-off-by: Gary Guo <gary@garyguo.net> Signed-off-by: Alice Ryhl <aliceryhl@google.com> Reviewed-by: Martin Rodriguez Reboredo <yakoyoku@gmail.com> Link: https://lore.kernel.org/r/20230531174450.3733220-1-aliceryhl@google.com Signed-off-by: Miguel Ojeda <ojeda@kernel.org>
