[WT-969] V2 Workflows for ImmutableProvider

[MitchSaadIMX]

Summary

This PR introduces a second set of workflow that support the new WalletConnection from the ImmutableProvider SDK

Why the changes

In order to use the new WalletConnection from the ImmutableProvider SDK, the workflows in core need to do a few things differently.

1. They need to accept the WalletConnection type
2. They need to resolve the signers they need from the WalletConnection (which may not always be there), and throw an exception if a required signer is missing.

Things worth calling out
