L0 Memory Leak on Windows in test-e2e\Graph\Explicit\reduction.cpp

[EwanC]

When run on Windows with the ZE_DEBUG=4 environment variable set, the test-e2e\Graph\Explicit\reduction.cpp test reports a memory leak of L0 resources, causing it to fail

               zeContextCreate = 1     \--->              zeContextDestroy = 0     ---> LEAK = 1
          zeCommandQueueCreate = 1     \--->         zeCommandQueueDestroy = 0     ---> LEAK = 1
                zeModuleCreate = 1     \--->               zeModuleDestroy = 0     ---> LEAK = 1
                zeKernelCreate = 2     \--->               zeKernelDestroy = 0     ---> LEAK = 2
             zeEventPoolCreate = 3     \--->            zeEventPoolDestroy = 0     ---> LEAK = 3
  zeCommandListCreateImmediate = 1     |
           zeCommandListCreate = 4     \--->          zeCommandListDestroy = 1     ---> LEAK = 4
                 zeEventCreate = 6     \--->                zeEventDestroy = 0     ---> LEAK = 6
                 zeFenceCreate = 4     \--->                zeFenceDestroy = 1     ---> LEAK = 3
                 zeImageCreate = 0     \--->                zeImageDestroy = 0
               zeSamplerCreate = 0     \--->              zeSamplerDestroy = 0
              zeMemAllocDevice = 1     |
                zeMemAllocHost = 1     |
              zeMemAllocShared = 0     \--->                     zeMemFree = 0     ---> LEAK = 2

This leak should be investigated and fixed

If I modify the reduction test to remove the graphs code I still see the memory-leak. Looking at existing e2e reduction tests I think this is a known issue unrelated to our extension intel#9764
