fix(iOS): `boxShadow + overflow hidden` combination affecting pointer event `box-none` and scale transform. (#52413)

Summary:
This issue is only reproducible with combination of `overflow: hidden` and `boxShadow` i.e. when a [container view](https://github.com/facebook/react-native/blob/2ce7eab5f998788ffa8346b63cc4901d026456ba/packages/react-native/React/Fabric/Mounting/ComponentViews/View/RCTViewComponentView.mm#L799) is added to the hierarchy.

### Case 1:

```jsx
<Pressable
  pointerEvents="box-none"
  style={{ width: 300, height: 300, boxShadow: "0 0 100px 0 rgba(0, 0, 0, 0.5)", overflow: "hidden" }}
  onPress={() => {
    alert("Tapped");
  }}
/>
```

Here the view has `box-none` but it will still trigger the press event because this [line](https://github.com/facebook/react-native/blob/2ce7eab5f998788ffa8346b63cc4901d026456ba/packages/react-native/React/Fabric/Mounting/ComponentViews/View/RCTViewComponentView.mm#L658) returns the `_containerView` as `hitView` and this condition gets [fullfilled](https://github.com/facebook/react-native/blob/2ce7eab5f998788ffa8346b63cc4901d026456ba/packages/react-native/React/Fabric/Mounting/ComponentViews/View/RCTViewComponentView.mm#L676) (since it is not self). To fix this issue we should iterate on `self.currentContainerView.subviews`.

### Case 2:

Transform scale clipping child view.

```jsx
<Pressable
  pointerEvents="box-none"
  style={{ width: 300, height: 300, overflow: "hidden",
    transform: [
      { scale: 0.5 },
    ],
    boxShadow: "0 0 100px 0 rgba(0, 0, 0, 0.5)",
  }}
  onPress={() => {
    alert("parent view");
  }}
>
  <Pressable
    style={{
      position: "absolute",
      bottom: 0,
      right: 0,
      backgroundColor: "blue",
      height: 50,
      width: 100,
    }}
    onPress={() => {
      alert("child view");
    }}
  >
    <Text>Press me</Text>
  </Pressable>
</Pressable>;
```

The above style hides the child view on iOS whereas it is visible on android.

This happens because `containerView` uses `self.frame` property which gets mutated due to scale transform. So containerView becomes `actualSize * scale * scale` instead of `actualSize * scale` and ends up clipping child views because of overflow hidden. Please checkout the layout hierarchy in the below screenshot. To fix it we need to use `self.bounds` instead of `self.frame` when setting the frame for container.
