Automatic update from web-platform-tests Refactor NavigateEvent state checks * Add a PerformSharedChecks() helper for entry point checks that apply to all functions on NavigateEvent (e.g., checking for detached window, whether the event is trusted, etc.) * Add a state machine for tracking interception state in NavigateEvent. Current states are None, Intercepted, Committed, Scrolled, Finished, and transitions must increase. This is hopefully easy to follow than the several independent booleans we are currently using. * Adding the state machine shows that it's possible to scroll before commit by calling scroll() during navigate event dispatch (and in fact, several tests do so). Fix that.
