[Feature]: Improve ParamFunction `Param` mock-ability

Feature Overview

Multiple Param implementation's mock functions allow an easy way to pass in data to a component's entry point, however many of these types (Such as Commands and ConfigMut) manipulate the data. We currently have no way to validate these changes post-component execution because these variables are consumed in the execution of the component.

Improvements should be made to be able to inspect the data after component execution to be able to do more comprehensive testing.

Solution Overview

Pass a reference to the data that will be manipulated by the Parameters, rather than consuming the instance. This allows us to still have access to the manipulated data after the component executes.

Alternatives Considered

Possibly do compile time configurations to change the inner data type when running tests.

Urgency
