Prepare tests for dexpreopt changes.

After this change, there is a clear separation between tests that are
related to dexpreopt and tests that are not. The former uses
PrepareForTestWithDexpreopt, while the latter uses
PrepareForTestWithJavaDefaultModules. The benefit is that the latter
will no longer affected by any dexpreopt changes.
