[clang-tidy] should ignore special names

like await_ready, await_suspend, await_resume etc. Such names must not provoke warning about incorrect naming

Start with clang-tidy's naming check and reproduce the warning for await_ready, await_suspend, and await_resume. Identify how the check classifies these names; done means these special names no longer trigger incorrect-naming warnings while other naming diagnostics remain unchanged.
