`PropertyPathRegistry` is responsible for uniqueing identifier and property paths. This is necessary for the hoistability CFG merging logic which takes unions and intersections of these nodes to determine a basic block's hoistable reads, as a function of its neighbors. We also depend on this to merge optional chained and non-optional chained property paths

This fixes a small bug in #31066 in which we create a new registry for nested functions. Now, we use the same registry for a component / hook and all its inner functions
