Depends on #15177

All jdk.internal.vm.Continuation instances will be handled specially by the GC

  • Add new scan type GC_ObjectModel::SCAN_CONTINUATION
  • Update scanners to detect this type
  • GC will need to scan the stacks of these types
    • for stackwalking, stack allocate j9vmthread, copy fields from j9vmcontinuation
