Request toolbar layout after drawable loads

Fixes #11209

Updating action items in a `ToolbarAndroid`, or more specifically the native `ReactToolbar`, after the initial render presently will not always work as expected - typically manifesting itself as new action items not being displayed at all (under certain circumstances).

This seems to be happening because Fresco gets back to us asynchronously and updates the `MenuItem` in a listener. However when a keyboard is displayed the `Toolbar` is in a weird state where updating the `MenuItem` doesn't automatically trigger a layout.

The solution is to trigger one manually.

This is a bit wacky, so I created a sample project:

`master` demonstrates the problem. Run the project, the toolbar action item is scheduled to update every 2 seconds. It works fine _until_ you give the `TextInput` focus. Once you give it focus the action item disappears and it never recovers (despite on-going renders due to state changes).

You can then checkout the `fixed` branch, run `yarn` again, and see that problem is fixed. This branch is using a prebuilt version of React Native with this patch applied. Of course you could (and probably should) also modify `master` to use a version of RN built by the Facebook CI (assuming that's a thing you guys do).
Closes #13876
