Expose `skimmed_fee_msat` in `PaymentForwarded`
We generally allow routing nodes to forward less than the expected HTLC
amount, if the receiver knowingly accepts this and claims the
underpaying HTLC (see `ChannelConfig::accept_underpaying_htlcs`). This
use case is in particular useful for the LSPS2/JIT channel setting where
the intial underpaying HTLC pays for the channel open.
While we previously exposed the withheld amount as
`PaymentClaimable::counterparty_skimmed_fee_msat` on the receiver side,
we did not individually provide it on the forwarding node's side.
Here, we therefore expose this additionally withheld amount via
`PaymentForwarded::skimmed_fee_msat`.

This will not be the case anymore and we need to pass the channel ID along
where appropriate. All channels that could have been persisted up to this

store a channel ID for them they can safely fall back to the funding

Fix final blinded hop CLTV expiry on send.

adds the shadow offset twice to the total path CLTV expiry. This 2nd offset
