OpenMP 5.1 introduces the new env variable OMP_TOOL_VERBOSE_INIT=(disabled|stdout|stderr|<filename>) to enable verbose loading and initialization of OMPT tools.
This env variable helps to understand the cause when loading of a tool fails (e.g., undefined symbols or dependency not in LD_LIBRARY_PATH)

Tests for this patch are integrated into the different existing tool loading tests, making these tests more verbose.
