  -----------
  [OpenMP] Improve omp offload profiler (#68016)

Summary:
Adding information to the LIBOMPTARGET profiler runtime kernel and API
calls.

Key changes:
* Adding information to runtime calls for better understanding of how
the application
is executing. For example teams requested by the user, size of memory
transfers.
* Profile timer was changed from 'us' to 'ns', since 'us' was too
coarse-grain
  to register some important details like key kernel duration
* Removed non API or Runtime calls, to reduce complexity of profile for
application
  developers.
