libhsakmt: add NumCpQueues and NumSdmaQueuesPerEngine data field (v3)
NumCpQueues and NumSdmaQueuesPerEngine should be got by kfd driver not hardcode. So add two data fields in HsaNodeProperties then thunk is able to get it from sysfs that exposed by kfd. v2: change NumCpQueues/NumSdmaQueuesPerEngine to one byte. v3: merge two commits as one to avoid ABI update two times.
