quic: implement stream flush

Do not commit data written to a stream to the network until
the user explicitly flushes the stream, the stream output
buffer fills, or the output buffer contains enough data to
fill a packet.

We could write data immediately (as net.TCPConn does),
but this can require the user to put their own buffer in
front of the stream. Since we necessarily need to maintain
a retransmit buffer in the stream, this is redundant.

We could do something like Nagle's algorithm, but nobody
wants that.

So make flushes explicit.

For golang/go#58547
