Switch hiddenapi to use OutputPath instead of ModuleOutPath

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.
