Add new type checker "bothOfType"

[Poyoman39]

This is a feature request:

With proptypes, we already have "oneOfType" type checker, what about a "bothOfType" type checker ?

What is the use case: You have these proptypes: const vehicle = propTypes.shape({ engine: propTypes.string }) const car = propTypes.shape({ engine: propTypes.string, wheels: propTypes.number })

It would be fine to be able to write it like that: const car = propTypes.bothOfType([vehicle, propTypes.shape({ wheels: propTypes.number })])

In case vehicle and car have a lot of properties it allows doing type refactoring.

What do you think about it ?

Note this already exists as and in https://npmjs.com/airbnb-prop-types (also note that shape always requires an object)
