Fix the AOSP (Soong) build: library wiring and API 36 skew

- Android.bp: pull in coil-compose 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: the screens report the chosen value to their
  onContinue callback; the wizard only advances, so adapt the lambda.
- SetupCompleteScreen: drawContent() needs the explicit drawWithContent
  receiver inside clipPath since the Compose receiver-scoping change.
