Gahow Wang 859c0cc0b6 distributed: NCCL P2P primitives (PpContext + send/recv) ...

Add ncclSend/ncclRecv FFI and a PpContext that initializes a NCCL
communicator across P pipeline stages and hands the hidden state to
neighbour stages on the null stream. Mirrors TpContext; the collective
differs (point-to-point hand-off vs in-layer AllReduce).

tests/sendrecv.rs: 2-GPU stage0->stage1 send/recv smoke test.
