* SDK: remove majority of exceptions

- replace with ROCP_FATAL, ROCP_CI_LOG(WARNING), etc.
- improve logging of symbolic link
- add --readlink and --realpath (hidden options) to rocprofv3 to follow symlinks for preloaded libraries

* Add rocprofv3 --rocm-root argument

* Fix registration resolved_exists

* Fix rocprofv3_avail.py

* Update logging for rocprofiler_configure search

- relax failure conditions

* Misc clang-tidy fixes
