Add CTSVerifier tests for checking permission grant states.

- Tests are added to check if permission is locked down in settings
depending on the state set by the device or profile owner.
- Moving CtsPermissionApp from cts/hostsidetests/devicepolicy/app
to cts/apps and using that for setting permission grant states.
