Allow self-referencing/recursive ts types

[chandlerprall]

Summary

@daveyholler encountered this bug while working on a recursive tree component. The types->proptypes generator would infinite recurse if an interface or type referenced itself, e.g.

interface Foo {
  children: Foo[];
}

This adds a check to verify we don't follow recursive references - for now this is done by resolving to a PropTypes.any as the object we would want to refer to doesn't exist (the JS code can't self-reference).

I verified this doesn't impact any existing components' proptypes by diffing the es and lib directories before and after the change.
