feat: add signal kill all functionality

2025-01-06T11:34:16Z

This change introduces the `lwp_signal_kill_all` function, which allows a signal to be sent to all processes in the system. The function iterates over all PIDs and sends the specified signal to each process, except those that are protected from signals. This enhancement provides a convenient way to broadcast signals across all processes in the system. Changes: - Added `lwp_signal_kill_all` function in `lwp_signal.c` to broadcast a signal to all processes by iterating over all PIDs using the existing `lwp_pid_for_each` function. - Introduced a new `kill_all_param` structure to encapsulate the signal information needed for killing processes. - Added internal `_kill_each` helper function for sending the signal to each PID. - Updated `lwp_signal.h` with the new function prototype for `lwp_signal_kill_all`. - Modified `sys_kill` in `lwp_syscall.c` to call `lwp_signal_kill_all` when a process is not specified.
