Fix the Soong build: restore library wiring, fix API 36 skew

- Android.bp: android-device-info is used by the wizard source (b11cf5b
  dropped it in error); re-add its android_library_import plus the
  core-splashscreen and coil-compose imports from
  prebuilts/application_libs, and a Soong-only BuildConfig stub under
  soong-stubs/ (Gradle generates its own, so the stub stays out of the
  Gradle source set).
- onNewIntent takes a non-null Intent on API 36.
- Region/Locale wizard pages pass a value-discarding lambda; the wizard
  only advances.
- SetupCompleteScreen: drawContent() needs the explicit drawWithContent
  receiver inside clipPath after the Compose receiver-scoping change.
