prevent scroll event in nested scroll when scrollEnabled={false} (#42219

)

Summary:
When a FlatList is in side a scroll view (think Netflix style navigation), the DPAD up/down fires on the scroll view, despite scrollEnabled={false} being set. This additiontially conflicts with any custom scroll event that has been created.

## Changelog:

[Android] [Fixed] - fix: prevent scroll event in nested scroll when scrollEnabled={false}

Pull Request resolved: #42219

Test Plan:
I tested this by making a ScrollView with FlatList of opposite scrolling direction inside with basic card layouts.

Both had scrollEnabled={false}

I scrolled the ScrollView myself as it has multiple rows using:

```
  const scrollToItem = React.useCallback(
    (itemIndex: number): void => {
      const targetScrollY = itemIndex * height
      scrollViewRef.current?.scrollTo({ y: targetScrollY, animated: true })
    },
    [height]
  )

  React.useEffect(() => {
    // Row 0, is global nav, but it's also the first row of cards
    // when we scroll to "1" what we mean is global nav is hidden
    // we should still be showing the first row of items.
    scrollToItem(rowIndex <= 1 ? 0 : rowIndex - 1)
  }, [rowIndex, scrollToItem])
```
