Avoid writing `ChannelManager` when hitting lnd bug 6039

When we hit lnd bug 6039, we end up sending error messages to peers
in a loop. This should be fine, but because we used the generic
`PersistenceNotifierGuard::notify_on_drop` lock above the specific
handling, we end up writing `ChannelManager` every time we manage a
round-trip to our peer.

This can add up quite quickly, and isn't actually changing, so we
really need to avoid writing the `ChannelManager` in this case.

Fix `Route` serialization round-trip

When the `max_total_routing_fee_msat` parameter was added to
`RouteParameters`, the serialization used `map` to get the max fee,

an `Option<u64>`. Thus, any `Route`s with a `route_params` written
will fail to be read back.

user managed to hit it.

Replace `EventsProvider` on `OnionMessageHandler` with a single fn

`OnionMessageHandler`s are expected to regularly release a set of
nodes which we need to directly connect to to deliver onion
messages. In order to do so, they currently extend
`EventsProvider`, returning that set as `Event::ConnectionNeeded`s.

While this works fine in Rust, the `EventsProvider` interface
doesn't map well in bindings due to it taking a flexible trait impl
as a method argument.

Instead, here, we convert `OnionMessageHandler` to include a single
function which returns nodes in the form of a `node_id` and
`Vec<SocketAddress>`. This is a bit simpler, if less flexible, API,

Fix final blinded hop CLTV expiry on send.

Previously, we were setting the final blinded hop's CLTV expiry height to
best_block_height + total_blinded_path_cltv_delta + shadow_cltv_offset. This is
incorrect, it should instead be set to best_block_height + shadow_cltv_offset
only -- it doesn't make sense to include the delta for the other blinded hops
in the final hop's expiry.

The reason this too-high final cltv value didn't cause test failures previously
is because of a 2nd bug that is fixed in an upcoming commit where the sender
adds the shadow offset twice to the total path CLTV expiry. This 2nd offset
meant that intermediate nodes had some buffer CLTV to subtract their delta from
while still (usually) have enough leftover to meet the expiry in the final hop's
onion.

Expose `onion_message` items directly rather than via re-exports

When we originally added the `onion_message` module, there weren't
a lot of public items in it, and it didn't make a lot of sense to
export the whole sub-module structure publicly. So, instead, we
exported the public items via re-exports directly in the
`onion_message` top-level module. However, as time went on, more
and more things entered the module, which left the top-level module
rather cluttered.

Worse, in 0.0.119, we exposed
`onion_message::messenger::SendSuccess` via the return type of
`send_message`, but forgot to re-export the enum itself, making
it impossible to actually use from external code.

Here we address both issues and simply replace the re-export with
the underlying sub-module structure.

Drop `PeerManager` type bound on `UtxoLookup` entirely

In 67659677d4fdb6bf418d66dfa37c61706425232b we relaxed the bounds
set on `UtxoLookup` to enable those using `RoutingMessageHandler`
other than `P2PGossipSync` to use `UtxoLookup`. Sadly, because this
requires having a concrete `PeerManager` type which does *not* use
`UtxoLookup` in the `RoutingMessageHandler` type, this broke users
who were directly using `P2PGossipSync`.

We could split `UtxoLookup` into two, with different bounds, for
the two use-cases, but instead here we simply switch to storing a
reference to the `PeerManager` via a `dyn Fn` which allows us to
wake the `PeerManager` when we need to.
