Refactor android_engine_test, make it easier to debug/deflake locally. (#161534)
The goal here is to have a great standalone `android_engine_test` suite
that [replaces
`scenario_app/android`](https://github.com/flutter/flutter/pull/160992).

No test is _functionally_ changed in this PR, but overview of changes:
- Finished renaming the suite `android_engine_tests` instead of
`flutter_driver_android`
- Added instructions and an environment variable for local generation of
golden-files (`UPDATE_GOLDENS=1`)
- Added explanations of the individual tests, where they live, and how
to run them locally
- Added a hybrid-composition (HC, not TLHC, which is already tested)
test
- Renamed "other_smiley" to "surface_texture_smiley" (and renamed the
original to "surface_producer_smiley")
- Removed unnecessary ".android" suffix (we will not run this on
anything but Android)
- Added a `tool/deflake.dart` to run a test suite 10x (or custom) times
locally to try and determine flakiness

After this PR, I'll add flags to let you control variants and name the
screenshots accordingly, i.e.:
- API v34 or v35
- OpenGLES or Vulkan (will require an `AndroidManifest.xml` edit during
the test instrumentation)

Automated Flutter integration test suites

Each suite consists of either a complete Flutter app and a flutter_driver specification that drives tests from the UI, or a native app that is meant to integrate with Flutter for testing.

Intended for use with devicelab tests.

If you want to run a driver test locally, to debug a problem with a test, you can use this command from the appropriate subdirectory:

flutter drive -t <test> --driver <driver>

For example:

flutter drive -t lib/keyboard_resize.dart --driver test_driver/keyboard_resize_test.dart
