Simplify deployment script

[longfeiWan9]

Currently, onramp uses deploy-onramp.fish to deploy onramp contract to Filecoin as well as other chains. It is a complicated process involving:

• setting up a Lotus node to deploy contracts
• not clear which contracts are supposed to be deployed to Filecoin or other chains.
• prover, oracle, and onramp contracts are coupled with each other
• unclear Xchain client key path

We should make this deployment process easier for regular builders, and easier to deploy to other chains when it is necessary.

The deployment steps should be:

Deploy contracts on different chains

1. Filecoin
   • deploy DealClient from Prover-Axelar.sol with args [_gateway, _gasReceiver] to set up Axelar for prover to call back.
2. SourceChain - Linea
   • deploy OnRampContract
   • deloy AxelarBridge from Oracle.sol with args[_gateway]

Wire contracts together

1. Filecoin
   • Calling DealClient.setDestinationChains() with info for Linea & other chains
2. SourceChain - Linea
   • Calling OnRampContract.setOracle(onrampAddressLinea) to wire Oracle to Onramp
   • calling AxelarBridge.setSenderReceiver(proverAddressFilecoin,onrampAddressLinea) so that Axelar knows where to call when sending cross-chain calls.

FYI. We would have to call addGasFunds() for Axelar call to succeed with an appropriate amount for cross-chain call and the same providerAddrData as a parameter that you will use while making a deal with xchain backend so that dealNotify() uses the funds you provided correctly.
