evaluate the reference() function as part of what-if evaluation

## Describe the noise

Today, what-if/preflight is not able to evaluate/compile the reference() function prior to doing the what-if comparison, which results in noise. On the PUT side, we show `reference().someProperty` and on the GET side we show the evaluated property (since it was evaluated to create the resource in the first place.

Will add incoming noise reports that relate to this to this thread

Start with the what-if/preflight comparison described in the issue and reproduce a resource using reference(). Trace how reference() is handled before the PUT/GET comparison. Done means the evaluated property is compared consistently on both sides without reference().someProperty noise.
