rocprofiler::counters::callback_thread_start does not issue pre_create/post_create callbacks

[jmellorcrummey]

rocprofiler::counters::callback_thread_start does not issue pre_create/post_create callbacks in the rocm 6.4.0 AFAR VII.

This causes hpctoolkit to try to monitor a pthread created as part of context initialization. That causes deadlock because hpctoolkit is in the middle of rocprofiler initialization and is not in a state where it can start monitoring a created thread.

Below is a callstack snippet to show where this problem occurs.
