GEODE-2161: avoid unnecessary byte copy of hdos.
> FilterRoutingInfo.FilterInfo.toData does unneeded copying

> Project: Geode
> Issue Type: Bug
> Reporter: xiaojian zhou
> Assignee: xiaojian zhou
>
> This is #52614
> FilterInfo.toData (that was being optimized for murex) does this:
> // create a hdos
> // write a bunch of stuff to it
> byte[] myData = hdos.toByteArray();
> DataSerializer.writeByteArray(myData, out);
> he toByteArray allocates a new byte array and copies all the data in the hdos
> to it.
> Then writeByteArray writes it all to "out".
> We can do this instead:
> if (out instanceof HeapDataOutputStream) {
> out.writeAsSerializedByteArray(hdos);
> } else {
> .. do it the old way
> }
