[wasm] Align raw Wasm URLs with disassembled ones

If script is not disassembled, still use the same script URL format for
consistency.

In particular, use an absolute `wasm://wasm/` prefix, like disassembled fake
scripts do, instead of just a script name which appears to be a
relative URL to devtools.
