Implement navigateEvent.intercept() and navigateEvent.canIntercept

Follows WICG/navigation-api#235 intercept() works very similarly to transitionWhile(), except that instead of taking a mandatory Promise, it takes an optional handler function. If a function is provided and it returns a promise, navigation finish will be delayed until the Promise resolve, just as transitionWhile() delays navigation finish for its Promise. canIntercept is identical to canTransition.
