Roctracer perfetto flow fixes (#267)

* testing label updates

- automatically add "gpu", "roctracer", "rocm-smi", and "rocprofiler" test labels when appropriate

* Bump version to v1.9.1

* roctracer and config updates

- fix perfetto::Flow
  - use roctracer correlation ID instead of critical trace correlation ID
- renamed ambiguous _cid, _parent_cid, _corr_id variables to _crit_cid, _parent_crit_cid, _roct_cid
- use atomic_{mutex,lock} instead of STL mutex/lock
- support for individual perfetto annotations for HIP API args
- OMNITRACE_PERFETTO_COMPACT_ROCTRACER_ANNOTATIONS option for controlling compact vs. individual perfetto annotations for HIP API args

* Update timemory submodule

- argparser updates
  - help prints to std::cout by default now
  - supports setting custom ostream

* cmake formatting

* config::get_setting_value updates

- config::get_setting_value returns std::optional instead of std::pair<bool, Tp>
