Add a new bumpforceclosefee rpc endpoint to the wallet server.
Move the logic from the lncli level to the wallet server rpc level.
This is more in line with a proper client-server design.
wallet lncli: use new bumpforceclosefee endpoint.
Besides using the new bumpforceclosefee rpc endpoint we also enable the
bumping of taproot anchor channels.
The RemoveTransaction endpoint removes the transaction with the
provided txid including all its descendants from the internal wallet.
We still keep watching for the address of the transation in case
the transcation is confirmed nonetheless. This command is particular
useful for neutrino backends because new bitcoind versions do not
reply with an invalid transaction error code when the tx published
fails to be included into the mempool (fullnodes do).
