Don't drop `ChannelMonitor` `Event`s until they're processed

We currently assume the owner of `ChannelMonitor`s won't persist

fine, except (a) its generally hard to do so and (b) the
`ChainMonitor` doesn't even do this.

Thus, in rare cases, a user could begin processing events which
are, generated by connecting a transaction or a new best-block,
take some time to do so, and while doing so process a further chain
event, causing persistece. This could lose the event being
processed alltogether, which could lose the user funds.

This should be very rare, but may have been made slightly more
reachable with (a) the async event processing making it more
common to do networking in event handling, (b) the new future
generation in the `ChainMonitor`, which now wakes the
`background-processor` directly when chain actions happen on the
`ChainMonitor`.

Add a `required_vec` TLV deserialization type

it is asymmetric and thus somewhat confusing - on the write side it
always writes a TLV entry, even if there are zero elements. On the

optional vecs. This adds the corresponding required form, always

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.
