RCCL support (#93)

* Initial support for RCCL

* OMNITRACE_USE_RCCLP + sampling tweaks

- also OMNITRACE_SAMPLING_KEEP_INTERNAL option
- minor modifications to sampling to use keep internal option + discard funlockfile

* Update docker and workflows to download RCCL

* Update CPack DEB with rocprofiler dependency

* Rework rccl into library and library/components folder

- add tpls/rccl/rccl/rccl.h

* Fix timemory includes

* rcclp inline definitions when disabled

* Tweaks to ubuntu-focal-external-rocm

- disable ompt
- enable building testing

* Tweaks to ubuntu-focal-external-rocm

- ctest exclude

* Tweak ubuntu-focal.yml

- remove source /.../setup-env.sh, replace with $GITHUB_ENV

* Fix ubuntu-focal-rocm + OMPI + root

* Improved rocm-smi error handling

- Recover from rocm-smi errors
- Disabling rocm-smi after recovering from errors
- Werror in developer mode
- Remove State::DelayedInit
- Add State::Disabled

* formatting

* Fix merge of OMNITRACE_SAMPLING_KEEP_INTERNAL

* Update RCCL include directory

- based on ROCm version we need with <rccl/rccl.h> or <rccl.h>

* RCCL Testing

- updated tests to use configuration files
- many tests generate a configuration file
- tests how have GPU option
- enable ncclCommCount, disable ncclGetVersion
- add testing for RCCLP via rccl-tests
- working directory of tests is PROJECT_BINARY_DIR
- add nccl/rccl functions to get_whole_function_names
- some clang compiler fixes

* Handle RCCL include w/o HIP

* RCCL requires HIP

* Update OMNITRACE_SAMPLING_CPUS for testing

* Update tests/CMakeLists.txt

* Debug settings

* Install MPI even when USE_MPI=OFF

* exclude printf

* skip mpi tests w/o USE_MPI or USE_MPI_HEADERS

* update ubuntu rocm workflow
