Justin Cohen 342bd4df0e ios: Enable extra_memory_ranges on iOS.
Port set_extra_memory_ranges support to iOS. Because iOS crashes
are processed in two parts, store the memory data itself (not just
the range) in the intermediate dump, and on post-crash processing,
move the memory to ProcessSnapshot ExtraMemory.
