StarlingMonkey WPT tests

[guybedford]

This enables the WPT tests for the StarlingMonkey port on CI.

In the process StarlingMonkey is updated to the latest version, including with the upstream fixes:

• https://github.com/bytecodealliance/StarlingMonkey/pull/69
• https://github.com/bytecodealliance/StarlingMonkey/pull/70
• https://github.com/bytecodealliance/StarlingMonkey/pull/71
• https://github.com/bytecodealliance/StarlingMonkey/pull/72

It also turns out StarlingMonkey was actually passing one extra WPT than our build. To resolve that this PR also updates our rust-url crate to the latest and to line up with StarlingMonkey's implementation, which replaces https://github.com/fastly/js-compute-runtime/pull/806. The remaining port TODOs are also completed here.
