Padding does not apply to Text nested inside another Text (iOS and Android).

Description

When trying to apply padding to a Text nested inside another Text, padding does not work.

Steps to reproduce

1. Write some text inside a Text.
2. Wrap a portion of the text with another Text.
3. Add padding to the nested Text. You can also add a backgroundColor to better see the padding.
   Result: Padding is not applied.

Screenshots and Videos

Start with the mandatory Snack reproducer and verify the nested Text padding behavior on iOS and Android. Then trace the React Native Text implementation and native text layout handling; done means padding is visibly applied to nested Text content on the affected platforms without regressing ordinary Text rendering.
