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.

MessageRouter trait for OnionMessenger
Add a trait for finding routes for onion messages and parameterize
OnionMessenger with it. This allows OnionMessenger to reply to messages
that it handles via one of its handlers (e.g., OffersMessageHandler).

Add OnionMessagePath wrapper struct
To avoid confusion in the upcoming MessageRouter trait, introduce an
OnionMessagePath struct that wraps the intermediate nodes and the
destination. Use this in OnionMessenger::send_onion_message.

OffersMessageHandler trait for OnionMessenger
Add a trait for handling BOLT 12 Offers messages to OnionMessenger and a
skeleton implementation of it for ChannelManager. This allows users to
either provide their own custom handling Offers messages or rely on a
version provided by LDK using stateless verification.

Onion message payload for BOLT 12 Offers
BOLT 12 Offers makes use of onion messages to request and respond with
invoices. Add these types and an error type to OnionMessageContents
along with the necessary parsing and encoding.

Pass logger to onion payload decoder
In an upcoming commit, messages for BOLT 12 offers are read from the
onion payload. Passing a logger allows for logging semantic errors when
parsing the messages.
