[OpenMP][OMPT] Implement verbose tool loading
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) Output of OMP_TOOL_VERBOSE_INIT is added for OMP_DISPLAY_ENV Tests for this patch are integrated into the different existing tool loading tests, making these tests more verbose. An Archer specific verbose test is integrated into an existing Archer test. Patch prepared by: Isabel Thärigen Differential Revision: https://reviews.llvm.org/D91464
