Create e2e test for apk-in-apex with a future minSdkVersion

Apk in apex should not be installed.

Test: atest ApkInApexTest

Test: (test the test:) manually change AndroidManifest.xml of the app and set
the min sdk version to 30. Repeat the test and the test should fail (because
with min sdk version 30, the app should be installable).

Bug: 208239394

Ignore-AOSP-First: feature not in AOSP yet

Change-Id: I7caa31fe366b74d74f1d8e9e53d6ddd241a70751
