    Make deSugarExpr use runTcInteractive
    
    Preparation for #13102, which needs to add more logic to
    runTcInteractive, which would need to be duplicated in deSugarExpr.
    
    In order to break an import cycle, I had to move
    "Dependency/fingerprinting code" to a new module
    DsUsage; which seems sensible anyways.
    
    Test Plan: validate
