Prevent `<Text />` `selectionColor` optimization bailout

[marklawlor]

The selectionColor prop will cause the Text -> NativeText optimization to bail out. Before the Text -> NativeText checks are made, we should attempt to remap selectColor={color} to import processColor from 'react-native/Libraries/StyleSheet/processColor';selectColor={processColor(color)}, and tag the attribute that it can be skipped in the Text -> NativeText optimization.
