FIO-9480: establish parent references before subform creation (5.0.x)

Description

Sometimes a deeply nested child needs state or data from a distant parent, and needs to crawl up the reference tree to get it. E.g. a calculated value that looks like

const myValue = instance?.root.parent?.root?.parent?.root?.parent?.data?.role;

Previously these references were not stable, because they were being instantiated after subForm creation. This PR fixes this behavior so that they are passed along with the creation options, and those references will be stable from the start.
