The ROCclr assigns zero-based IDs to GPUs in the order they are
discovered. That zero-based ID is what is used to identify the GPU
on which the HIP_OPS activity took place.
When multiple ranks are used, each rank's first logical device always
has GPU ID 0, regardless of which physical device is selected with
CUDA_VISIBLE_DEVICES. Because of this, when merging trace files from
multiple ranks, GPU IDs from different processes may overlap.
The long term solution is to use the KFD's gpu_id which is stable
across APIs and processes. Unfortunately the gpu_id is not yet exposed
by the ROCr, so for now use the driver's node id.

Remove the activity_prof::CallbacksTable. The table was redundant with
the information already stored in the roctracer library. Instead use a
single callback into the roctracer library to query whether the activity
is enabled, and to report it.

The activity_ is only instantiated if profiling is enabled.
Remove the HIP private global record ID. Instead, use the correlation ID
stored in the hip_api_data_t by the profiler while the last HIP function
is in scope.
For NDRange and Copy commands, store the kernel name and byte size
(respectively) in the record.
General cleanups to improve the code's readability.
