[SYCL] Add coarse-grained debug aid for finding imbalance in Level-Zero alloc/free (#3334)

A sample output is this:

ZE_DEBUG=4: check balance of create/destroy calls
----------------------------------------------------------
zeContextCreate = 1     \--->              zeContextDestroy = 1
zeCommandQueueCreate = 1     \--->         zeCommandQueueDestroy = 1
zeModuleCreate = 1     \--->               zeModuleDestroy = 1
zeKernelCreate = 1     \--->               zeKernelDestroy = 1
zeEventPoolCreate = 8     \--->            zeEventPoolDestroy = 8
zeCommandListCreateImmediate = 1     |
zeCommandListCreate = 2     \--->          zeCommandListDestroy = 3
zeEventCreate = 2000  \--->                zeEventDestroy = 2000
zeFenceCreate = 2     \--->                zeFenceDestroy = 2
zeImageCreate = 0     \--->                zeImageDestroy = 0
zeSamplerCreate = 0     \--->              zeSamplerDestroy = 0
zeMemAllocDevice = 0     |
zeMemAllocHost = 0     |
zeMemAllocShared = 0     \--->                     zeMemFree = 0

Also fixed a bug in piEnqueueEventsWait where we were allocating a command-list but never closed/released it.
