Disable auto-resumption in Java

This CL removes the auto-resumption logic from Java since the functionality
is now handled in native using AutoResumptionHandler.
1 - Added a feature DownloadAutoResumptionInNative
2 - Disabled the network observer and auto-resumption logic in DownloadMangerService
3 - Disabled resumption task scheduling through DownloadResumptionScheduler
