SWDEV-351980 - Consolidate registration tables in the roctracer library

Remove the api_callbacks_table_t that was holding the API activities and
user callbacks. Instead use a single roctracer callback (TracerCallback)
used to report both API activities and callbacks.

Remove the hipInitActivityCallback that was setting the ROCtracer
callback and memory pool for asynchronous activities as it did not
allow disctinct pools to be used for each activity.  Instead, use
hipRegisterTracerCallback to set the single roctracer callback.
