In order to allow the hiddenapi code which expects its inputs to be ModuleOutPath to consume the output from the deapexer module type (used by prebuilt_apex) this change converts the hiddenapi from using ModuleOutPath to use OutputPath instead. This is part of a general cleanup to remove ModuleOutPath that is separated out in order to avoid having the hiddenapi work dependent upon and possibly delayed by issues with that general cleanup.
