It is sometimes more useful to have a string of the errno name ("INVAL") than the docs ("Invalid argument." This PR updates witx-bindgen to create functions for errno_name(u16) -> &'static str and renames strerror to errno_docs(u16) -> &'static str. The name is used in Error's Display impl, and both are provided in the Debug impl.
