Update default dust exposure limit and the documentation thereof

Now that we're including excess counterparty commitment transaction
fees in our dust calculation, we need to update the docs
accordingly. We do so here, describing some of the considerations
and risks that come with the new changes.

We also take this opportunity to double the default value, as users
have regularly complained that non-anchor channels fail to send
HTLCs with the default settings with some feerates.

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.

Introduce ResponseInstructions for OnionMessage Handling

- Currently, handle_message (or handle_custom_message) only exposes
  the generated response for an OnionMessage, lacking the necessary
  reply_path for asynchronous responses.

- This commit introduces a new flow for OnionMessage handling.

- Instead of solely taking the message as input, handle_message now accepts
  an Optional `responder`, returning a `ResponseInstruction` containing both
  the response and the reply_path.

- `ResponseInstruction` utilizes different enum variants to indicate how
  `handle_onion_message_response` should handle the response.

- This enhancement enables exposing the reply_path alongside the response
  and allows for more complex response mechanisms, such as responding with
  an added reply_path.

- The commit introduces the foundational framework (structs & enums) for this new flow.
