Add support for signal-related types/functions in wrapped_facade_headers

[coderabbitai]

Request

Add support in wrapped_facade_headers for signal-related types and functions (e.g., kill, sigaction, sigemptyset, std::sig_atomic_t, pid_t).

Background

In the Spider project, we're using signal handling functions and types for graceful termination when receiving signals like SIGTERM. Currently, we have to add linter suppressions (NOLINTNEXTLINE(misc-include-cleaner)) when using these functions:

// Send SIGTERM to task executor
pid_t const pid = spider::core::ChildPid::get_pid();
if (pid > 0) {
    // NOLINTNEXTLINE(misc-include-cleaner)
    kill(pid, SIGTERM);
}

Similarly for using sigaction, sigemptyset and other signal-related functions:

// NOLINTBEGIN(misc-include-cleaner)
struct sigaction sig_action{};
sig_action.sa_handler = stop_task_handler;
sigemptyset(&sig_action.sa_mask);
sig_action.sa_flags |= SA_RESTART;
if (0 != sigaction(SIGTERM, &sig_action, nullptr)) {
    spdlog::error("Fail to install signal handler for SIGTERM: errno {}", errno);
    return cSignalHandleErr;
}
// NOLINTEND(misc-include-cleaner)

Implementation suggestion

Add appropriate wrappers in wrapped_facade_headers for:

• kill function from <signal.h>/<csignal>
• sigaction, sigemptyset and other signal handling functions
• Signal-related types like pid_t and std::sig_atomic_t

This issue was identified during review of y-scope/spider#104, which implements graceful exit when receiving SIGTERM.
