* User API + reorganized lib folders

- omnitrace_user_start_trace
- omnitrace_user_stop_trace
- omnitrace_user_start_thread_trace
- omnitrace_user_stop_thread_trace
- omnitrace_user_push_region
- omnitrace_user_pop_region

* New OpenMP examples/tests

* Fix to KokkosP

* OMPT support

- fixed omnitrace instrumenting reporting
- common invoke improvements
- component::user_region

* exclude kmp_threadprivate_

* Separate omnitrace into multiple files

* PTL and timemory submodule updates

* Active guards + USE_OMPT guards in omnitrace-dl

* Tweak transpose default iterations

* omnitrace-precommit build target

* Omnitrace exe restructuring pt 2

- Never instrument functions with less than 4 instructions
- Never instrument ompt_start_tool or nanosleep
- module_function serializes heuristics
- removed hash stuff from omnitrace
- removed instr_procedures lambda
- WAITPID_DEBUG_MESSAGE

* set_state, "_hidden" fix, CI exceptions, backtrace fix

- set_state function
- fixed "_hidden" from appearing in print macros using __FUNCTION__
- OMNITRACE_CI_THROW
- more CI checks in library
- fixed backtrace init value sample issue being ignored

* Tweaks to OMPT tests

* cmake-formatting

* Removed debug output from backtrace processing

* Fix warnings and verbosity

* omnitrace-dl fix for libomp

* omnitrace-avail fixes

- remove second omnitrace_init_library call
- fix -r option not working

* Additional testing

- source/bin/tests
- tests for omnitrace-exe
- tests for omnitrace-avail

* cmake-format

* Reduce runtime of openmp-lu

* Update openmp-lu and tests timeout

* openmp-lu and CI tweaks

- decrease iterations
- OMP_NUM_THREADS=2
- install clang and libomp-dev in linux-ci
- fix data-files in linux-ci
