Add support for memoized components

[rafaelfbs]

Issue: #6298

What I did

Fix component code and component prop table to display info of memoized components. React encapsulates a memoized component as an object with property "type".

How to test

• Is this testable with Jest or Chromatic screenshots? Yes, I added a jest test scenario.
• Does this need a new example in the kitchen sink apps? No.
• Does this need an update to the documentation? No.
