Perform a gesture

Performs a named gesture — pinch, rotate, pan, swipe, doubletap, longpress or tap. The gesture is first offered to a matching MAUI gesture recognizer on the target element or its ancestors. If there is none, it is injected natively at the platform view, which is how pinch-to-zoom reaches controls that handle gestures internally such as Map, WebView and native scroll views. The response reports which tier serviced the gesture so callers can tell a real recognizer hit from a native fallback. Tap requires elementId; other gesture types target the current page when it is omitted.
