WORK IN PROGRESS (PROTOTYPE) - DO NOT REVIEW
Description
This PR proposes a prototype for introducing an asynchronous verbose mode to accurately track kernel execution times for GPU engines. For the verbose mode, retrieving the kernel timing causes significant overhead as it requires the GPU kernel execution to be synchronized and also because it is tracked on the host.
The asynchronous mode uses event-based tracking to measure the GPU kernel execution to avoid the synchronization issue.
The prototype is created for SYCL/OCL GPU APIs that provide the kernel execution statistics for profiling.
Addresses MFDNN-12088.
