Create a real type for protocol.DocumentURIs. Remove span.NewURI in favor of path/URI-specific constructors. Remove span.Parse's ability to parse URI-based spans, which appears to be totally unused. As a consequence, we no longer mangle non-file URIs to start with file://, and crash all over the place when one is opened. Updates golang/go#33699.
