This populates information on both topology (i.e. unannounced channels) and capacity for the local node using `listpeerchannels`.

We don't know anything about most channels, so we create an array of
fp16_t containing them. We zero out ones where we do know something,
and use the previous code as the slow path.

This means we never have to look up a local channel when asked the capacity.
We mark these dummy constraints with an MAX timestamp.

We apply all the gossmods for the layers they specified, and create a
naive routine to give the capacity of a channel given those layers.
