LibWeb: Implement PromiseRejectionEvent

Browse source 
This paves the way for the rejectionhandled and unhandledrejection
events.

It's also used by core-js (in browsers, at least) to check whether
Promise needs to be polyfilled, so adding it should allow more websites
to leverage LibJS's native Promise implementation :^)
