Linting workflow and clang-tidy fixes (#72)

* Update source/{bin,lib/{common,rocprofiler}}/CMakeLists.txt

- activate clang-tidy

* Update PTL submodule

- clang-tidy fixes

* Update .clang-tidy

- ignore performance-enum-size

* Update CI workflow

- update paths-ignore

* Add linting workflow

- runs clang-tidy

* Update cmake/rocprofiler_build_settings.cmake

- minor modification of flags not recognized by clang-tidy

* Update samples (all of them)

- rocprofiler-samples-build-flags target with -W -Wall -Wextra -Wshadow [-Werror]
- Link samples targets to rocprofiler-samples-build-flags if target exists
- Remove unused variable in main.cpp of api_{buffered,callback}_tracing
- Update samples/pc_sampling
  - single-user-multiple-agents.cpp ends up with unused function find_first_gpu_agent() error
  - change find_first_gpu_agent to return std::optional<rocprofiler_agent_t>
  - change usage after call to find_first_gpu_agent()
  - use find_first_gpu_agent() in single-user-multiple-agents.cpp to determine if there are any GPUs

* Update linting workflow

- fix path to run-ci.py script

* Update linting workflow

- install cmake

* Update common/container/stable_vector.hpp

- fix clang-tidy warning for readability-container-size-empty
