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.

Provide a default CoinSelectionSource implementation via a new trait

Certain users may not care how their UTXOs are selected, or their wallet
may not expose enough controls to fully implement the
`CoinSelectionSource` trait. As an alternative, we introduce another
trait `WalletSource` they could opt to implement instead, which is much
simpler as it just returns the set of confirmed UTXOs that may be used.
This trait implementation is then consumed into a wrapper `Wallet` which
implements the `CoinSelectionSource` trait using a "smallest
above-dust-after-spend first" coin selection algorithm.

Add BumpTransaction event handler

This allows users to bump their commitments and HTLC transactions
without having to worry about all the little details to do so. Instead,
we'll just require that they implement the `CoinSelectionSource` trait
over their wallet/UTXO source, granting the event handler permission to
spend confirmed UTXOs for the transactions it'll produce.

While the event handler should in most cases produce valid transactions,
assuming the provided confirmed UTXOs are valid, it may not produce
relayable transactions due to not satisfying certain Replace-By-Fee
(RBF) mempool policy requirements. Some of these require that the
replacement transactions have a higher feerate and absolute fee than the
conflicting transactions it aims to replace. To make sure we adhere to
these requirements, we'd have to persist some state for all transactions
the event handler has produced, greatly increasing its complexity. While
we may consider implementing so in the future, we choose to go with a
simple initial version that relies on the OnchainTxHandler's bumping
frequency. For each new bumping attempt, the OnchainTxHandler proposes a
25% feerate increase to ensure transactions can propagate under
constrained mempool circumstances.

`OnchainTxHandler` when a commitment is broadcast/confirmed. This
requires making it public in our API. We also choose to rename it to
`ClaimId` for the benefit of users, as the previous `PackageID` term
could be interpreted to be the ID of a BIP-331 transaction package.
