LibWeb: Define PerformanceEventTiming https://www.w3.org/TR/event-timing/#sec-performance-event-timing Add idl, header and stubs for PerformanceEventTiming interface. Two missing `PerformanceEntry` types that have come up in issues are the `first-input` and the `event` entryTypes. Those are both this. Also, because both of those are this same interface, the static methods from the parent class are difficult to implement because of instance-specific details. Might either need subclasses or to edit the parent and also everything that inherits from it :/ 2024-09-22 16:12:55 -03:00			`[Exposed=Window]`
