Description

Implements a GpuEventSynchronizer class for SYCL.

There is no way to do this efficiently within the SYCL standard. With DPC++, this implementation relies on SYCL_EXT_ONEAPI_ENQUEUE_BARRIER extension, which directly enqueues a CUDA-like barrier event. With AdaptiveCpp, it relies on ACPP_EXT_ENQUEUE_CUSTOM_OPERATION extension to submit an empty operation (that can have dependencies and returns an event).
