Fix an issue with removeClippedSubviews and TextInput 

Summary:This issue was found by brentvatne in https://github.com/facebook/react-native/issues/6805

The problem is an ordering issue.  The internal state of the TextView (Editor) is updated when we set the text value for a ReactTextInput. When removeClippedSubviews is false, we addView the view which attaches it to the window, and then set the text. When removeClippedSubviews is false, we defer adding the view (caching it in mAllChildren in ReactViewGroup) until we know whether the view is actually going to show.  This means when we set the initial text, that there is no window attached.  Not having a window attached means that the Editor can't display the popup for PASTE and thinks that the text is not selectable and won't respond to the long press.  To fix this we explicitly call setTextIsSelectable in onAttachedToWindow.  This will cause the underlying TextView to have the Editor update and all will be in agreement.

Note:
This also makes it really easy to expose a selectable property on both Text and TextInput at the js level now.
