For now, bpf_get_func_arg() and bpf_get_func_arg_cnt() is not supported by the BPF_TRACE_RAW_TP, which is not convenient to get the argument of the tracepoint, especially for the case that the position of the arguments in a tracepoint can change. The target tracepoint BTF type id is specified during loading time, therefore we can get the function argument count from the function prototype instead of the stack.
