Prioritise UITapGestureRecognizer on interop views with Cooperative interop mode. Prioritise UIScreenEdgePanGestureRecognizer on ascendant views.

Before that change taps on interop views with cooperative mode would be discarded by compose, which expects non-discrete gesture holding on a point before failing and redirecting touches sequence to the interop view.

The requirement of holding ultimately made the tap gesture impossible due to its requirement of being a short press/release sequence, which contradicts the compose heuristics.

This scenario is fixed in this PR by allowing precedence of UITapGestureRecognizer over other recognisers.

Since most of the native tap/double tap interactions are built on top of UITapGestureRecognizer it should improve the UX for default interop properties with stable constructor setting the interaction mode to be Cooperative.

Coincidentally this change inspired a cheap fix for interactive pop bugs.

Testing

• Taps on interop views with cooperative interaction mode are properly registered now and processed by native UITapGesture recogniser attached to that view.
• Interactive pop on UINavigationController should not get stuck in an awkward state preventing the gesture.

This should be tested by QA

Release Notes

Fixes - iOS

• Taps should be properly registered on interop views with UIKitInteropInteractionMode.Cooperative interaction mode.
• Interactive pop on UINavigationController should recognize correctly.

Unfortunately, it fixes the swipe back only partially. STRs:

• Create UINavigationController with some rootViewController
• Push Compose View Controller
• Slowly swipe back, and cancel gesture, by returning to the the current Compose View Controller
• Perform some interaction with Compose View Controller
• Try to swipe back again
  Result: Swipe back does not work.

Because the issue considered as critical, and the fix make the overall experience better, I think it worth adding it to the 1.7.2 release. Also, due to complexity of the interop gestures, I would not go with dramatical changes in the frature's code.
The issue should be fixed in 1.8.0.
