feat: Add tabIndex prop to View component

[gabrieldonadel]

Summary

This adds the tabIndex Android only prop to View as requested on https://github.com/facebook/react-native/issues/34424 mapping the existing focusable prop to tabIndex so that tabIndex={0} maps to focusable={true} and tabIndex={-1} represents focusable={false}.

[Android] [Added] - Add tabIndex prop to View component

Test Plan

I'm still investigating the best way to test this but we're are just mapping this to an existing prop
