Use Gradle Managed Devices to run unit tests on Android runtime

  Switch android-test module from JVM tests to androidTest with Gradle
  Managed Devices (ATD API 30). Reuses existing unit tests from
  src/test/java/api/ via sourceSets. CI workflow boots headless emulator
  via pixel2api30DebugAndroidTest to catch ICU regex incompatibilities.
