stream_buffer: require batching buffers to exceed trigger level

Batching stream buffers are documented to unblock receivers only after the buffered byte count exceeds the trigger level, but both xStreamBufferSend() paths currently notify as soon as the count reaches it.

That equality case wakes the blocked receiver too early, causing xStreamBufferReceive() to return 0 bytes while the buffer still holds exactly trigger-level data. Route both task and ISR send paths through a shared trigger helper so batching buffers require a strict greater-than check while existing stream and message buffer semantics remain unchanged.

Fixes #1375
