Add helper functions to verify node and channel annoucements

Right now the only real way to verify the node and channel
announcements is to call `update_node_from_announcement`/
`update_channel_from_announcement`. If you want to do some
processing before you add to your network graph then you need to
manually verify the signature. This adds some nice helper functions
to make it easier.

I tried to do the same for channel update but it did not seem as
easy so figured that is fine to punt on since I don't see many
people doing manual things with channel updates.

Re-claim forwarded HTLCs on startup

Because `ChannelMonitorUpdate`s can complete asynchronously and
out-of-order now, a `commitment_signed` `ChannelMonitorUpdate` from
a downstream channel could complete prior to the preimage
`ChannelMonitorUpdate` on the upstream channel. In that case, we may
not get a `update_fulfill_htlc` replay on startup. Thus, we have to

Add max dust exposure multiplier config knob

With fee rates rising dramatically in mid-April 2023, thresholds for
what is considered dust have risen, often exceeding our previous dust
exposure threshold of 5k sats. This causes all payments and HTLC
forwards between 5k sats and new dust thresholds to fail.

This commit changes our max dust exposure config knob from a fixed
upper limit to a `MaxDustHTLCExposure` enum with an additional variant
to allow setting our max dust exposure to a multiplier on the current
high priority feerate.

To remain backwards compatible we'll always write the fixed limit if
it's set, or its default value in its currently reserved TLV.

We also now write an odd TLV for the new enum, so that previous
versions can safely ignore it upon downgrading, while allowing us to
make use of the new type when it's written.

Move Channel's blocked monitor updates vec to an even TLV

In 9dfe42cf8681afc9c3f84e0c85a4e2a30c1156a8,
`ChannelMonitorUpdate`s were stored in `Channel` while they were
being processed. Because it was possible (though highly unlikely,
due to various locking likely blocking persistence) an update was
in-flight (even synchronously) when a `ChannelManager` was
persisted, the new updates were persisted via an odd TLV.

However, in 4041f0899f86eaf6a0a4576a91918fa54026ac46 these pending
monitor updates were moved to `ChannelManager`, with appropriate
handling there. Now the only `ChannelMonitorUpdate`s which are
stored in `Channel` are those which are explicitly blocked, which
requires the async pipeline.

Because we don't support async monitor update users downgrading to
0.0.115 or lower, we move to persisting them via an even TLV. As
the odd TLV storage has not yet been released, we can do so
trivially.

Fixes #2317.
