Test and document Image resizeMode=center on iOS

Summary:
`<Image resizeMode="center">` already works on iOS (implemented in #8792), but is neither tested nor documented the way the other `resizeMode` values are.

This PR primarily enables the relevant RNTester case on iOS, and secondarily copies over the doc comment from `Image.android.js` to `Image.ios.js`. A PR to `react-native-website` will follow shortly and it is there I will try and revise the wording a bit.

Updated RNTester screenshot (iOS):

react-native-website PR coming soon.
