Force-close channels if their feerate gets stale without any update

For quite some time, LDK has force-closed channels if the peer
sends us a feerate update which is below our `FeeEstimator`'s
concept of a channel lower-bound. This is intended to ensure that
channel feerates are always sufficient to get our commitment
transaction confirmed on-chain if we do need to force-close.

However, we've never checked our channel feerate regularly - if a
peer is offline (or just uninterested in updating the channel
feerate) and the prevailing feerates on-chain go up, we'll simply
ignore it and allow our commitment transaction to sit around with a
feerate too low to get confirmed.

Here we rectify this oversight by force-closing channels with stale
feerates, checking after each block. However, because fee
estimators are often buggy and force-closures piss off users, we
only do so rather conservatively. Specifically, we only force-close
if a channel's feerate is below the minimum `FeeEstimator`-provided
minimum across the last day.

Further, because fee estimators are often especially buggy on
startup (and because peers haven't had a chance to update the
channel feerates yet), we don't force-close channels until we have
a full day of feerate lower-bound history.

This should reduce the incidence of force-closures substantially,
but it is expected this will still increase force-closures somewhat
substantially depending on the users' `FeeEstimator`.

Switch to using the `OnionMessenger` directly in BP

When `OnionMessenger` first developed a timer and events interface,
we accessed the `OnionMessenger` indirectly via the `PeerManager`.
While this is a fairly awkward interface, it avoided a large pile
of generics on the background processor interfaces. However, since
we now have an `AOnionMessenger` trait, this concern is no longer
significant. Further, because we now want to use the built-in
`OnionMessenger` async event processing method, we really need a
direct referene to the `OnionMessenger` in the background
processor, which we add here optionally.

Add a parallel async event handler to `OnionMessenger`

This adds an `OnionMessenger::process_pending_events_async`
mirroring the same in `ChannelManager`. However, unlike the one in
`ChannelManager`, this processes the events in parallel by spawning
all futures and using the new `MultiFuturePoller`.

Because `OnionMessenger` just generates a stream of messages to
store/fetch, we first process all the events to store new messages,
`await` them, then process all the events to fetch stored messages,
ensuring reordering shouldn't result in lost messages (unless we
race with a peer disconnection, which could happen anyway).

Store `OnionMessenger` events in different `Vec`s

In the next commit, `OnionMessenger` events are handled in parallel
using rust async. When we do that, we'll want to handle
`OnionMessageIntercepted` events prior to
`OnionMessagePeerConnected` ones.

While we'd generally prefer to handle all events in the order they
were generated, if we want to handle them in parallel, we don't
want a `OnionMessageIntercepted` event to start being processed,
then handle an `OnionMessagePeerConnected` prior to the first
completing. This could cause us to store a freshly-intercepted
message for a peer in a DB that was just wiped because the peer
is now connected.

This does run the risk of processing a `OnionMessagePeerConnected`
event prior to an `OnionMessageIntercepted` event (because a peer
connected, then disconnected, then we received a message for that
peer all before any events were handled), that is somewhat less
likely and discarding a message in a rare race is better than
leaving a message lying around undelivered.

Thus, here, we store `OnionMessenger` events in separate `Vec`s
which we can pull from in message-type-order.
