SWDEV-538195 - Introduce threshold for handler submission (#723)

- When doing device/stream sync, we can submit a handler which may
  introduce some host side delays. Use DEBUG_CLR_BATCH_CPU_SYNC_SIZE to
  batch commands for host wait. Default for HIP is 8 commands.
- Investigation is underway in ROCr but need to address this for now in
  HIP runtime.
