> Add a tracepoint to monitor TCP send operations, enabling detailed
> visibility into TCP message transmission.
>
> Create a new tracepoint within the tcp_sendmsg_locked function,
> capturing traditional fields along with size_goal, which indicates the
> optimal data size for a single TCP segment. Additionally, a reference to
> the struct sock sk is passed, allowing direct access for BPF programs.
> The implementation is largely based on David's patch[1] and suggestions.
