Summary: NativeAnimated currently depends on folly::dynamic event payloads for event-driven animations. While some events (e.g., ScrollEvent.h) have an `asDynamic` implementation, not all events do. Having the ability to convert an EventPayload to a folly::dynamic defined on the EventPayload implementations precludes generalized event handling in NativeAnimated. This change moves the `asDynamic` method from `ScrollEvent` to the base `EventPayload` interface, defaulting the implemention to returning a null value. ## Changelog [Internal] Reviewed By: zeyap Differential Revision: D71046682
Summary: We have listeners for EventDispatcher, but we don't have any listener capabilities for synchronous hooks from events on the UI thread. This proposal adds an affordance for generic event listeners that can be attached by the host platform mounting manager, e.g., to wire events to NativeAnimated event drivers. ## Changelog [Internal] Differential Revision: D71050838
