[dtest] Enhancing hipStreamAddCallback() api test

-Scenario-1:: This test case is used to verify if the callback function called through hipStreamAddCallback() api completes the execution in order as hipStreamAddCallback() api queued in their respective streams: hipStreamACb_AltEnqueue.cpp -Scenario-2:: This test case tests if Host thread continues with next command after hipStreamAddCallback() api or wait for callback() call to finish. Ideally Host thread should not wait for callback to finish: hipStreamACb_ThrdBehaviour.cpp -Scenario-3:: Streams are launched in individual GPUs with different kernel Verify that all the kernels queued are executed before the callback is hit: hipStreamACb_MStrm_Mgpu.cpp -Scenario-4:: Checks the callback execution in the same order it was added. Also, it checks if the number of callbacks executed are same as the number of callbacks added: hipStreamACb_order.cpp -Scenario-5:: This test case checks whether hipStreamSynchronize() is taking less time than the time taken by Callback() function launched by hipStreamAddCallback() api : hipStreamACb_StrmSyncTiming.cpp -Scenario-6:: This test case is used to check if the runtime is ok when hipStreamAddCallback() is called back to back multiple calls: hipStreamACb_MultiCalls.cpp -Scenario-7:: This test case is used to check the behaviour of HIP when multiple hipStreaAddCallback() are called over multiple Threads:hipStreamACb_MultiThread.cpp (Currently disabled) SWDEV-238517 for enhancing hip unit tests Change-Id: I9c7b7df6766c728b2b201df18726b9fbdd434c06
