nested text onPress not working on last character (#30928)

Summary:
This issue fixes https://github.com/facebook/react-native/issues/22747 nested text does not allow you to press on the last character.

The method reactTagForTouch filters touches based on coordinates x and y. Nested Texts are converted into Spans on Android
https://github.com/facebook/react-native/blob/28fb41a0ab48cc01d606b64744c84e2ac3805f3f/ReactAndroid/src/main/java/com/facebook/react/views/text/ReactBaseTextShadowNode.java#L111-L112
https://developer.android.com/guide/topics/text/spans

reactTagForTouch iterates over the span and triggers the onPress handler if the x,y coordinates correspond to one of the span characters.

Pull Request resolved: https://github.com/facebook/react-native/pull/30928

Test Plan:
This changes fix the Java API which can not be tested as explained in commit https://github.com/facebook/react-native/commit/709a441ecf54cd9465f5946af0454ee7d10d5cbe
The java TextTest was excluded from the test suite in commit https://github.com/facebook/react-native/commit/709a441ecf54cd9465f5946af0454ee7d10d5cbe as they need the Yoga libraries to run
