Mitigate int overflow in findNextFocusableElement (facebook#54291)

Summary:
Pull Request resolved: facebook#54291

We are computing a weighted distance by squaring the major and minor axis distance. For particularly long lists, this means that items that are quite far away have a tendency to overflow the int value when squared, producing a negative number that becomes the smallest weighted distance.

Switching the computed value to double should mitigate the issue, since MAX_DOUBLE >>> MAX_INT ^ 2.
