[contract-deploy] Universal deploy methods for instance deployer

[spalladino]

Add the "universal deploy" methods, one private and one public, to the instance deployer. These methods just call back into the instance deployer, and are meant to have a consistent msg-sender for contracts that are meant to have the same address regardless of who deploys them.

Implement via a flag in the method. Depends on #4434.
