Allow vertical overflow for Text with numberOfLines={1}

[mozzius]

Setting numberOfLines on Text causes the text to get clipped in both axis, which means if you have a smaller line height it might clip ascenders/descenders. Exaggerated example:

The fix is to use overflow-inline: clip instead of overflow: hidden, so that it just clips it in the horizontal axis. This matches React Native's behaviour on iOS/Android. Unfortunately this only works for single-line clamps - to my knowledge it's unfixable for multi-line clamps.

overflow-inline is baseline newly available, if that's a problem we could use overflow-x: clip instead. However, that wouldn't support vertical writing modes :/. If that's an unreasonable compromise, feel free to put this PR on ice for however many years it takes to become widely available :)
