phase: apply publishing enforcement for "serve" source

When a changegroup is added from a push on a publishing server, we ensure they
are added as public. This is used to enforces publishing on server when the
client is not aware of phases. It also prevents race condition where a reader
could see the changeset as draft before they get turned public by the client.
Finally this save rounds trip as the client does not need additional request to
turn them public.

However this logic was only enforced when the changegroup was from "push"
source. And "push" is used for local pushes only. Wireprotocol push use "serve"
as source since Mercurial 1.9. We now enforce this logic for both "push" and
"serve" sources.

One could notes that this logic was mainly useful during wireprotocol exchanges.
So this code is finally put into good use, 9 version after its introduction.
