SYCL/Basic/event_profiling_info.cpp flakily failing on CUDA/HIP

This test was disabled on CUDA some time ago ( https://github.com/intel/llvm-test-suite/pull/230 ) But no issue was opened. It looks to be some sort of memory leak, and therefore should not be forgotten.

I rechecked it today and it continues to fail flakily. This is the error I see on a failure:

```
PI CUDA ERROR:
Value: 2
Name: CUDA_ERROR_OUT_OF_MEMORY
Description: out of memory
Function: cuda_piContextCreate
Source Location: /iusers/cperkins/sycl_workspace/llvm/sycl/plugins/cuda/pi_cuda.cpp:2095

terminate called after throwing an instance of 'sycl::_V1::runtime_error'
what(): Native API failed. Native API returns: -6 (PI_ERROR_OUT_OF_HOST_MEMORY) -6 (PI_ERROR_OUT_OF_HOST_MEMORY)
```
