[Native] Fix shouldCancelWhenOutside not tracking the view (#3942)

## Description

Addresses the underlying issue of
#3906

The original issue described in the above PR was caused by wrong shadow
node dimensions, which were fixed by
#3930.
After that, the dimensions were good, but the long press was still
failing. This was caused by `shouldCancelWhenOutside` checking the
dimensions of the detector while the child was moved.

This PR changes the logic so that the child's hitbox is checked when
using the native detector. This should be enough for iOS, but on
Android, further investigation is needed into whether the entire
`transformedEvent` should be in the coordinate space of the detector or
its child.

## Test plan
