SWDEV-504494 - Use system scope for D2H

- When using shader copy, make sure to use release scope for the AQL
  packet. This is a potential bug but is hidden as hipMemcpyAsync always
needs synchronization(which inserts a barrier with release scope). For
hipMemcpy we use a barrier packet to make sure its blocking. Eitherways
a barrier gets always used and hides in some ways a potential bug.
