Include excess commitment transaction fees in dust exposure

Transaction fees on counterparty commitment transactions are
ultimately not our money and thus are really "dust" from our PoV -
they're funds that may be ours during off-chain updates but are not
ours once we go on-chain.

Thus, here, we count any such fees in excess of our own fee
estimates towards dust exposure. We don't bother to make an
inbound/outbound channel distinction here as in most cases users
will use `MaxDustExposure::FeeRateMultiplier` which will scale
with the fee we set on outbound channels anyway.

Note that this also enables the dust exposure checks on anchor
channels during feerate updates. We'd previously elided these as
increases in the channel feerates do not change the HTLC dust
exposure, but now do for the fee dust exposure.

Drop completed blocked `ChannelMonitorUpdate`s on startup

If a user receives a payment preimage for an outbound payment, the
`PaymentSent` event will block any eventual RAA
`ChannelMonitorUpdate` from the same channel, assuming it comes in
before the event can be processed. If this blocking kicks in, but
the flow eventually completes with the RAA `ChannelMonitorUpdate`
being persisted, but the `ChannelManager` is only persisted prior
to the event being handled, on startup we'll have a fully
up-to-date `ChannelMonitor` but a pending, blocked
`ChannelMonitorUpdate`. When the `PaymentSent` event is replayed
we'll end up trying to apply a redundant `ChannelMonitorUpdate`
which will panic.

See the test added in this commit for an implementation of this
situation.

In this commit we fix this issue by simply dropping blocked
`ChannelMonitorUpdate`s the same as we do pending ones.
