the witness_script could be derived here rather than passed in, if I'm not mistaken

failing here likely indicates a serious internal error, so should propagate the error to the caller

…TxCache Used in next commits to avoid passing script between ChannelMonitor and OnchainTxHandler. ChannelMonitor duplicata will be removed in future commits.
As we can't predict if any and which revoked commitment tx is going to appear onchain we have by design to cache all htlc information to regenerate htlc script if needed.
As we cache more and more transaction elements in OnchainTxHandler we should dry up completly InputMaterial until them being replaced directly by InputDescriptor
By moving script generation inside OnchainTxHandler, we may dry-up further ChannelMonitor in next commits.

Build on top of #559 + #560 + #561.
Once merged, we don't have hot private keys anymore in OnchainTxHandler/ChannelMonitor :)
