gossip_store: change format so we store raw messages. Save some overhead, plus gets us ready for giving subdaemons direct store access. This is the first time we upgrade the gossip_store, rather than just discarding. The downside is that we need to add an extra message after each channel_announcement, containing the channel capacity.

gossip_store: make private channels more similar to channel_announcement Instead of a boutique message, use a "real" channel_announcement for private channels (with fake sigs and pubkeys). This makes it far easier for gossmap to handle local channels. Backwards compatible update, since we update old stores. We also fix devtools/dump-gossipstore to know about the tombstone markers. Since we increment our channel_announce count for local channels now, the stats in the tests changed too.

gossip_store: create end marker for EOF. This is better than using the previous "keep statting the file" approach, since we can also tell you how long the replacement is, to avoid a gratitous load.

gossipd: don't close non-local channels immediately, add 12 block delay. This adds a new "chan_dying" message to the gossip_store, but since we already changed the minor version in this PR, we don't bump it again.
