Move Quic Stream data writing from WriteCodec to PacketBuilder

Browse Source 
Summary:
Different Builders now want to have its own way of writing or
appending write buffer. So let builders handle them.

This also add new APIs in BufWriter to copy data from IOBuf/BufQueue directly
into a destination IOBuf without cloning inbetween.
