Add support for profiler hooks in logger

[upsj]

Tools like TAU or NVIDIA Toolkit Extensions allow applications to log custom events/phases in a nested fashion. We could profit from their tooling by providing loggers wrapping this functionality.

This is definitely a good idea. I think we already had some effort from @tcojean using PAPI with software defined events.

Additionally, there are a few libraries that can abstract this for different backends as well. This would allow us to for example to have a common instrumentation functions in our code and have that work for different backends that the library uses. Just to mention some libraries which might be useful for this:

1. Tau,
2. Score-P
3. Caliper.

Of course, we always have the option of using the profiler API that Nvidia and ROCM (and DPC++ ? ) provide, but that might be more work and maintenance.
