Heschi Kreinick f7b8cc7bd0 internal/span,lsp: disambiguate URIs, DocumentURIs, and paths
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.
