Delete un-tested hybrid_android_views, add layering to android_engine_test. (flutter#162903)

Another large test suite that has never been running.

The underlying thing I _think_ it wanted tested, which was hybrid
composition, is now tested by `android_engine_test`. I also added a red
square on top of each platform view so that, like
`hybrid_android_views`, we can make sure layering is working as
expected.

Any other ideas? Can also be follow-up PRs?
