[WIP] foundry based tooling for yield backend ops

[d10r]

This PR adds tooling for deploying and enabling yield backends.
Much of the code added here is generic and to be used for other ops too going forwarded (related to truffle being deprecated).

Typically setting up a yield backend involves the following steps:

• deploy a new yield backend
• create gov action for setting the SuperToken admin to the gov owner
• create admin action for enabling the yield backend

(The second step is needed because unlike for updateCode, there's no code in the host and governance contract for calling the permissioned functions for controlling a yield backend.
Meaning, for SuperTokens using a yield backend, the governance owner directly interacts with the SuperToken contract, without the calls being routed through 2 other contracts. This may change in the future, e.g. in case many SuperTokens get a yield backend, and/or if the current contract size limit is lifted)

Here's the commands used to deploy yield backends and create related gov/admin actions for USDCx on 2 networks:
