HTTP/2: optimized queuing of DATA frames

With priorities from RFC 9218, streams of the same urgency are ordered
by their identifiers, so queuing a frame of an older stream traverses
the frames of all newer ones.

Frames queued in ngx_http_v2_send_chain() belong to a single stream, and
hence to a single position in the output queue, which does not change
while they are queued.  Now the position is searched once per call.
