* Added GN flag v8_enable_zone_compression.
* AccountingAllocator supports allocation of zone segments via both
  malloc/free and bounded page allocator. The latter implementation is
  known to be not efficient yet. This issue will be addressed in a
  follow-up CLs.
* Add support_compression flag to Zone constructor/instance.
