Single tap not processed on time

[adrianv-synergy]

Description

For a multi-gesture setup, the single-tap finalization is delayed until all touches are released. It wouldn't be a problem unless we are talking about touches outside the tracked area, which should be otherwise ignored.

In its simplest setup, we can have a list with a ScrollView and a double & single tap combination. Now when the scroll view has an active touch, any additional touches to the tracked area only process the double-tap gesture. Single-tap is only finalized once the initial touch over the list is released. Even worse - when operating with one touch point only, single-tap finalization is delayed until the scroll`s momentum movement is completed.

I've tested 0.78 and 0.75.4 RN versions, both new & old architecture, with and without react-native-reanimated. Tried to work it out by using RNGH ScrollView and simultaneous gestures, but it didn't make a difference.

Feels like it's a native iOS issue with gesture recognition. Works fine on Android under all scenarios.

Steps to reproduce

1. Scroll the list outside a GestureDetector with enough momentum
2. Single-tap within the GestureDetector area - onBegin will be called
3. Observe that onEnd/onFinalize won't be called until scroll`s momentum completes

---

1. Press and hold on a list outside a GestureDetector to initiate scrolling
2. Single-tap (second touch-point) within the GestureDetector area - onBegin will be called
3. Observe that onEnd/onFinalize won't be called until first touch over the scroll is released.

Expected outcome for both scenarios: - process gesture and call onEnd/onFinalize immediately after touch release within the gesture tracking area.
