Add a stack reference

<p>
See
{@link TraceReferenceManager#addStackReference(Lifespan, Address, int, RefType, SourceType, int)}
regarding potential confusion of the word "stack" in this context.

@param creationSnap the starting snap
@param from the from address
@param to the to stack offset
@return the reference
