LibWeb: Add an Internals API to trigger a user-activated (trusted) event

Browse source 
Some DOM APIs are restricted to user-activated events. For example, you
can't just invoke `navigator.clipboard.writeText` from JS - it has to be
accompanied by a user gesture, such as a mouse-down event. This adds an
Internals API to simulate such a gesture.
