multi: add bumpforceclosefee rpc endpoint.

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.
