[api-minor] Limit the PDFDocumentLoadingTask.onUnsupportedFeature functionality to GENERIC builds (PR 15758 follow-up)

Browse source 
This was deprecated in PR 15758 but it's unfortunately quite difficult to tell if third-party users are depending on this, e.g. to implement custom error reporting, and if so to what extent.
However, thanks to the pre-processor we can limit *most* of this code to GENERIC builds which still seem like a worthwhile change.

These changes reduce the bundle size of the Firefox PDF Viewer by 3.8 kB in total.
