RN Android: Support View Manager Commands that are strings

Browse Source 
Summary:
Right now JS triggers a view manager command with the following code:

```
UIManager.dispatchViewManagerCommand(
  ReactNative.findNodeHandle(this),
  UIManager.getViewManagerConfig('RCTView').Commands.hotspotUpdate,
  [destX || 0, destY || 0],
);
```

As we want to get rid of calls to UIManager, we need to stop looking for the integer defined in native from JavaScript. We will be changing methods like this to be:

```
UIManager.dispatchViewManagerCommand(
  ReactNative.findNodeHandle(this),
  'hotspotUpdate',
  [destX || 0, destY || 0],
);
```

We need to support ints and Strings to be backwards compatible, but ints will be deprecated.
