Add support for selectionColor on Android TextInput

Summary:
public
This adds support to set the highlight color on TextInput on Android.  See https://github.com/facebook/react-native/pull/5678 for the iOS implementation.

Note : We will merge these two properties with one name 'selectionColor' in a follow on diff, and may move it to a style.
