Fix test dependencies for AppEnumerationInternalTests

All of a test's dependencies should be explicitly declared in the Soong build module to enable infrastructure features that ensure correctness and optimize runtime. Here in the test config file, AppEnumerationInternalTests uses `AppEnumerationSyncProviderTestApp.apk`, so that this change declares `AppEnumerationSyncProviderTestApp` in the Soong build module.

Besides, this change modifies the test config file by switching to use `PushFilePreparer` instead of `FilePusher`, since `FilePusher` is designed for the tests that are part of compatibility suite and AppEnumerationInternalTests is not.
