[v2] UISplitViewController (#3247)

* Work in progress

* Arbitary changes

* Improvements on API

* Cleanup RNNSplitViewController, allow mergeOptions

* Added documentation and better playground example

* Adding tests for coverage

* Find out why this test is failing.

* Only show split view on iOS

* Add test back in

+```js
+const splitView = {

+    minWidth: 150, // Minimum width of master view
+    maxWidth: 300, // Maximum width of master view
