This breaks the `script_traits` dependency on `webgpu`. In general, the `traits` crates shouldn't depend on Servo non-`traits` crates. This is necessary to move "script to constellation" messages to the `constellation_traits` crate, making it the entire API for talking to the constellation. This will break a circular dependency when that happens. Testing: Successfully building is enough of a test for this one as it is mainly moving types around.
