CocoaPods doesn't support multiple Swift modules in the same pod.
Build COpenCombineHelpers sources together with OpenCombine sources
as a single module.
Previously COpenCombineHelpers was a separate pod. This was suboptimal,
as it made making changes in both targets very hard: you'd have to
push COpenCombineHelpers to trunk in order to pass validation.
