refactor[renderer]: expose getInspectorDataForInstance in rendererConfig (#26913)

## Summary
This is required for the case when we have an instance and want to get
inspector data for it. Such case occurs when RN's application being
debugged via React DevTools.

React DevTools sends instance to RN, which then gets all auxiliary data
to highlight some elements. Having `getInspectorDataForInstance` method
exposed makes it possible to easily get current props from fiber, which
then can be used to display some margins & paddings for hovered element
(via props.style).

I see that `getInspectorDataForInstance` is being exported at the top
level of the renderer, but feels like this should also be inside
DevTools global hook, the same way we use it for
[`getInspectorDataForViewAtPoint`](e7d3662904/packages/react-native/Libraries/Inspector/getInspectorDataForViewAtPoint.js).
