Add ESLint check for incorrect propTypes usage

See #3818 (comment).
This depends on jsx-eslint/eslint-plugin-react#1647 getting resolved.

I'm following up on the eslint-plugin-react issue and can fix this when that's done.

I've submitted a PR to eslint-plugin-react to add the functionality we need: jsx-eslint/eslint-plugin-react#1655.

My PR to eslint-plugin-react has been merged. I'm just waiting for it to be released and then I'll add this to create-react-app.
