Add an additional test/bench for routing larger amounts, score more

When benchmarking our router, we previously only ever tested with
amounts under 1,000 sats, which is an incredibly small amount.
While this ensures we have the maximal number of available channels
to consider, it prevents our scorer from getting exercise across
its range. Further, we only score the immediate path we are
expecting to to send over, and not randomly but rather based on the
amount sent.

Here we try to make the benchmarks a bit more realistic by adding
a new benchmark which attempts to send around 100K sats, which is
a reasonable amount to send over a channel today. We also convert
the scoring data to be randomized based on the seed as well as
attempt to (possibly) find a new route for a much larger value and
score based on that. This potentially allows us to score multiple
potential paths between the source and destination as the large
route-find may return an MPP result.

Allow holding `ChannelMonitorUpdate`s until later, completing one

In the coming commits, we need to delay `ChannelMonitorUpdate`s
until future actions (specifically `Event` handling). However,
because we should only notify users once of a given
`ChannelMonitorUpdate` and they must be provided in-order, we need
to track which ones have or have not been given to users and, once
updating resumes, fly the ones that haven't already made it to
users.

To do this we simply add a `bool` in the `ChannelMonitorUpdate` set
stored in the `Channel` which indicates if an update flew and
decline to provide new updates back to the `ChannelManager` if any
updates have their flown bit unset.

Further, because we'll now by releasing `ChannelMonitorUpdate`s
which were already stored in the pending list, we now need to
support getting a `Completed` result for a monitor which isn't the
only pending monitor (or even out of order), thus we also rewrite
the way monitor updates are marked completed.

Currently `BackgroundProcessor` tests create persister directories in the
current working directory and rely on cleaning up in a `Drop` implementation.

Unfortunately, it seems that in the async tests that nodes are not
`drop()`ed for some reason and so the directories created by those
tests remain behind in the current working directory.

a temporary location for the OS using `temp_dir()`. It doesn't aim to
solve the lack of cleanup in the async tests.

Partial fix for #2224 but I believe it's enough to resolve it as these
temp directories that do remain will be purged by the OS at some stage
and are overwritten by subsequent tests if there is a conflict.

Don't remove nodes if there's no channel_update for a temp failure

Previously, we were requiring any `UPDATE` onion errors to include
a `channel_update`, as the spec mandates[1]. If we see an onion
error which is missing one we treat it as a misbehaving node that
isn't behaving according to the spec and simply remove the node.

Sadly, it appears at least some versions of CLN are such nodes, and
opt to not include `channel_update` at all if they're returning a
`temporary_channel_failure`. This causes us to completely remove
CLN nodes from our graph after they fail to forward our HTLC.

While CLN is violating the spec here, there's not a lot of reason
to not allow it, so we go ahead and do so here, treating it simply
as any other failure by letting the scorer handle it.

[1] The spec says `Please note that the channel_update field is
mandatory in messages whose failure_code includes the UPDATE flag`
however doesn't repeat it in the requirements section so its not
crazy that someone missed it when implementing.

Check for `background-processor` exit condition before+after sleep

In a synchronous `BackgroundProcessor`, the exit is done by setting
an atomic flag, which is most likely to happen while we're asleep.
Thus, we previously checked for the exit condition after the sleep
(and after we persisted the `ChannelManager`, if required, though
this is no longer required and dates back to when we didn't do a
re-persist after breaking out of the main loop).

For an async `background-processor`, this is also fine, however
because of the relatively longer sleep time, if the exit flag is
set via a sleep check returning true during event processing, we
may end up delaying exit rather substantially.

In order to avoid this, we simply check for the exit condition both
before and immediately after the sleep in `background-processor`.
