Set usesNonSdkApi in manifest when Platform_apis=true

The Platform_apis field in CompilerDeviceProperties currently has no
effect. Unify the behaviour with make and run manifest_fixer.py to
encode the information in the manifest. This is used to exempt
bundled apps and platform tests from hidden API access checks without
having a fixed whitelist of packages.
