[iOS] Fix Pressable onPressOut callback (#3777)

## Description

Currently `onPressOut` is not called when `Pressable` gestures are
cancelled. `iOS` and `android` are different when it comes to order of
callbacks. In that particular case, when gesture is cancelled, on
`android` we first receive `onTouchesCancelled`. However, on `iOS`
`onFinalize` is called first. Inside `handleFinalize` function
`isCurrentlyPressed` is reset to false, which means that `onPressOut`
will not be called when we enter `onTouchesCancelled` callback. The
thing is, in that place we don't have information required for event, so
it is not possible to call `handlePressOut` from this place.

In this PR, I disabled calling `handleFinalize` on `iOS` in `onFinalize`
callback, so that it calls `handlePressOut` when inside
`onTouchesCancelled` callback. It also aligns with `android`
implementation, as now the flow is the same.

Fixes #3769

## Test plan

Tested on:

- `Pressable` examples on `expo-example` app.
