This is the final step of #1799, where the majority of the generated code for the JS bindings is now compiled as part of the script_bindings build step. The remaining pieces in script must live there because they refer to concrete DOM types; all code in script_bindings is generic over the [DomTypes](https://doc.servo.org/script/dom/bindings/codegen/DomTypes/trait.DomTypes.html) trait. My testing with incremental builds shows me a 12 second reduction in build times on my 2024 M4 Macbook Pro when modifying code in the script crate after these changes. Before this PR those changes took 20 seconds to rebuild Servo, and now they take 8 seconds. Testing: Existing WPT tests ensure no regressions.
