Build transaction should support soroban functionalities

[janewang]

We need to add a few operations

• Restore Footprint: https://developers.stellar.org/docs/learn/fundamentals/transactions/list-of-operations#restore-footprint
• Extend Footprint TTL: https://developers.stellar.org/docs/learn/fundamentals/transactions/list-of-operations#extend-footprint-ttl
• Invoke Host Function: https://developers.stellar.org/docs/learn/fundamentals/transactions/list-of-operations#invoke-host-function
  • Show a warning message if other operations are added to the transaction. Invoke Host Function can't have any other operations.
  • On the Submit Transaction page, check if the XDR contains an Invoke Host Function to allow submission only via RPC.

Any chance we can prioritize this. When I tried to invoke Blend protocol (mainnet), I got the error that my user data entry has been archived. If lab had a way to restore the entry I could try that. I think a lot of users will start facing this issue.

Discussed and we will prioritize Restore Footprint and Extend Footprint TTL first.
