mptcp: implement TCP_NOTSENT_LOWAT support
Add support for such socket option storing the user-space provided
value in a new msk field, and using such data to implement the
_mptcp_stream_memory_free() helper, similar to the TCP one.
To avoid adding more indirect calls in the fast path, open-code
a variant of sk_stream_memory_free() in mptcp_sendmsg() and add
direct calls to the mptcp stream memory free helper where possible.
Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/464
