* Add parser createParenthesizedExpressions option …
When set to `true` we create `ParenthesizedExpression` nodes instead of
setting `extra.parenthesized`.
* Also update babel-parser.d.ts
In https://github.com/babel/babel/issues/9511 (and #9495 is another symptom), @PavelKastornyy reported a node crash becaue the JavaScript heap run out of memory. The problem was that their code was adding enumerable properties to `Object.prototype`: it is something that shouldn't be done, but Babel shouldn't make node crash if someone adds them.
I reduced down the problem to `for...in` loops in `@babel/traverse` that grew the memory consumption exponentially because of that unexpected properties.
