[roll] Roll fuchsia [input] Handlers update InputHandlerStatus fields for events handled.

Create count_handled_event that updates events_handled_count on a
handler's dedicated inspect node. This should be called by a handler
upon consuming a received input event.

Add support for counting handled events to Input Handlers that consume events.
