Changes our cipd hosted android sdk+ndk bundle to no longer modify directory structure from what Android directly provides, allowing AGP to find the ndk automatically and preventing downloading. 1. Changes the `create_cipd_packages.sh` script so we don't move the ndk 2. Uses the new script to upload a [36v4unmodified](https://chrome-infra-packages.appspot.com/p/flutter/android/sdk/all/linux-amd64/+/version:36v4unmodified) bundle 3. Changes DEPS+ci.yaml to reference the new bundle 4. Changes GN build rules accordingly 5. Removes special config in existing build.gradle files to point at the location of the ndk - agp should now know where it is without conig 6. For some tests, passes in an environment variable pointing to the ndk location, to override the environment variable passed by the recipes. This variable is respected by the tool, so the recipes passing it, pointing to the wrong place, is problematic. After this change lands we can stop passing it in the recipes, and then we can remove this special config in the tests. But adding it temporarily allows us to make this change without coordinating a recipes change at the same moment, and probably breaking things out of band.

Integration test for touch events on embedded Android views
This test verifies that the synthesized motion events that get to embedded Android view are equal to the motion events that originally hit the FlutterView.
The test app's Android code listens to MotionEvents that get to FlutterView and to an embedded Android view and sends them over a platform channel to the Dart code where the events are matched.
This is what the app looks like:
The blue part is the embedded Android view because it is positioned at the top left corner, the coordinate systems for FlutterView and for the embedded view's virtual display has the same origin (this makes the MotionEvent comparison easier as we don't need to translate the coordinates).
The app includes the following control buttons:
- RECORD - Start listening for MotionEvents for 3 seconds, matched/unmatched events are displayed in the listview as they arrive.
- CLEAR - Clears the events that were recorded so far.
- SAVE - Saves the events that hit FlutterView to a file.
- PLAY FILE - Send a list of events from a bundled asset file to FlutterView.
A recorded touch events sequence is bundled as an asset in the assets_for_android_view package which lives in the goldens repository.
When running this test with flutter drive the record touch sequences is
replayed and the test asserts that the events that got to FlutterView are
equivalent to the ones that got to the embedded view.
