The extra_memory_ranges stored in the intermediate dump and used by gwp-asan via the ProcessSnapshot are not needed in the minidump. If this memory were stored in the minidump with gwp-asan, this would double the size of every iOS minidump. Instead, add a second bag that is stored in the intermediate dump but not written to the minidump. Expose an iOS only ProcessSnapshot API that can be used by the gwp-asan analyzer to use the extra_memory_ranges without increasing the minidump file size.
