Currently, when debugging wasm, the internal script URL is shown, which
has the form wasm://wasm/wasm-<hex-script-id>. With this change, if the
module specifies a module name, it would report the URL as
wasm://wasm/<module-name>-<hex-script-id>, as this will help the user
identify what they are debugging.
