e4e75462 - [SYCL][UR] Fix CUDA and HIP semaphore and image copy event recording (#21075)

[SYCL][UR] Fix CUDA and HIP semaphore and image copy event recording (#21075) This commit fixes event recording for the following functions in the CUDA and HIP UR adapters: - urBindlessImagesImageCopyExp - urBindlessImagesWaitExternalSemaphoreExp - urBindlessImagesSignalExternalSemaphoreExp Previously, start was not called on the event and the return value of record was ignored. The test that should benefit from this fix is https://github.com/intel/llvm/blob/sycl/sycl/test-e2e/bindless_images/vulkan_interop/unsampled_images_timeline_semaphore.cpp. My own test app runs the copy operation for 100 times, and without the fix from this PR, a race condition can be seen about 3 in 100 times. So it may take a while to see the issue in `unsampled_images_timeline_semaphore.cpp`, which only runs the copy operation once.
