[SYCL][CUDA][HIP] Block until the event is ready to start profiling. (#9938)

* Call to `hipEventElapsedTime` return `hipErrorNotReady` when the
timestamp has not yet been `recorded` on one or both events. Calling
`hipEventSynchronize` block until the event is ready.
* The issue showed itself when profiling sycl-blas benchmark.
* Enable support for cuda / hip in event_profiling_info.cpp
