wireprotov2: send content encoded frames from server
Now that we have support for negotiating encodings and configuring
an encoder, we can start sending content encoded frames from the
server.
This commit teaches the wireprotov2 server code to send content
encoded frames.
On the mozilla-unified repository with zstd enabled peers, this change
reduces the total amount of data transferred from server to client
drastically:
befor: 7,190,995,812 bytes
after: 1,605,508,691 bytes
