John Knox 173ce43192 Add sample app layout snapshot test
Summary:
This is fairly experimental. The test passes, but I don't know how stable it will be when litho changes for example.

However, it's easy to exclude specific attributes from the hierarchy, so maybe we can iterate if it breaks at first.

It just takes a snapshot of the layout hierarchy from headless flipper, and compares it to it's known one.

To run it:
`cd headless-tests && DEVICE=emulator-5554 yarn test` while you have the sample app running on an emulator.

To update the snapshots, just add `-u` to the end of that command.
