Fix review issues: boolean comparison, missing trigger, constants

- Fix benchmarks CI condition: 'true' not 'True' (jq outputs lowercase)
- Add script/setup_codspeed_lib.py to benchmark infrastructure triggers
- Extract BENCHMARK_INFRASTRUCTURE_FILES and BENCHMARKS_COMPONENTS_PATH
  as top-level constants in determine-jobs.py
- Fix extra_include_dirs docstring
