CFNetwork fixed rdar://problem/34745171 in iOS 13 and macOS 10.15, which means that WebKit no longer needs the workaround of adding “NSURLSessionResumeInfoLocalPath” to resume data before creating a download task. However, the OS conditional in Download::resume() is set up so that non-Mac builds and 10.15-or-later Mac builds still attempt that workaround in the #else block. This workaround doesn’t have any effect (since CFNetwork changed the internal format of the resume data in macOS Mojave / iOS 12), and its presence only leaves the potential for a bug in the future if the format of the resume data blob is significantly changed in the future. We should remove this “workaround”. (keeping the first part of the #if/else around for Mojave)
