Move interfaces of component of service to internal

Move interfaces of component to internal.
To make codebase build pass,
1. Remove makeAppDetailsActivity of ParsedActivity, make
ParsedActivityImpl.makeAppDetailsActivity to be public and use it instead.
2. Change all imports that used those interfaces.
To fix tests failed with ClassNotFoundException
1. PackageImpl: get class loader from ParsedProcessImpl instead of
ParsedProcess.
2. ParsedPermissionImpl: get class loader from ParsedPermissionGroupImpl
instead of ParsedPermissionGroup.
