apex/apk: enforce min_sdk_version of all deps

Enforce min_sdk_version for every payload dependency of updatable
APEX/APKs.

android.CheckMinSdkVersion() calls ApexModule.ShouldSupportSdkVersion
for every transitive dependency from APEX/APK modules to see if it
meets the min_sdk_version requirements.

The common implementation for apex/android_app is provided in
android/apex.go.
