getCsrForLowPriority will always return a CSR with a compute engine
regardless of the ordinal used. When a copy-only ordinal is used to
create a command queue or command list, batch buffers are written using
BCS style commands rather than CCS style. This caused BCS commands to be
submitted to a low-priority compute engine which was invalid. This patch
ensures a copy engine is selected when a copy-only ordinal is used even
if ZE_COMMAND_QUEUE_PRIORITY_PRIORITY_LOW is specified.
