Add EstimateFees function before deploy a workflow

[chrisli30]

There should be an estimateFees function like prior to Ethereum transaction submission:

Input should include:

1. nodes and edges,
2. createdAt
3. expireAt
4. maxExecution

Output should include:

1. Gas fee estimated based on ContractWrite and LoopNodeContractWrite which will need to pay for EVM transaction fees
2. Automation fee esitmated based on trigger type and task duration
3. First-time smart wallet AA contract creation fees.
4. Any promotion of fee reduction.
