Assuming that the dex layout optimization is now fully integrated (guarded by an experimental property), we should add end-to-end testing to validate that the minimal startup dex generated by R8 is complete when using a Macrobenchmark.

For example, we could take the "Empty Compose Activity" project from the "New Project" wizard, and:

1. Extend the project by:

   1. Enabling R8

   2. Adding a Macrobenchmark test that launches the app

   3. Setting android.experimental.r8.dex-startup-optimization=true

2. Run the Macrobenchmark test to generate a startup-prof.txt

3. Assemble the release variant of the app.

4. Remove classes2.dex from the generated apk.

5. Launch the app on an emulator or a device and verify that the app does not crash.

If step (5) fails after removing classes2.dex it means that we did not correctly include all startup classes in classes.dex (assuming that the app is deterministic).
