Mike Grabowski edf8888fb9 Platform.select method
Summary:
Kudos to frantic for this amazing idea! Works really well (yet so simple!)

Basically we had a discussion with vjeux and frantic and others in the PR #7033 how to handle platform-specific stylesheets in a similar to F8 app way.

There were quite a few nice ideas there, however that one seems to be the smallest yet the most powerful.

Basically there's a `Platform.select` method that given an object, will select a `obj[Platform.OS]` value.

It works with styles:
`Platform.select({ ios: {}, android: {} })`

with messages:
`<Text>{Platform.select({ ios: 'Check the App Store', android: 'Check Google Play' })}</Text>`

and also works well with components (similar to Wallmart idea of <PlatformSwitch />) - relevant example included in diff.
Closes https://github.com/facebook/react-native/pull/7220
