When set to `true` we create `ParenthesizedExpression` nodes instead of
setting `extra.parenthesized`.

* add partial application syntax and some tests
* remove unnecessary error message and hasPartial function from parseNewArguments
* add types for PartialExpression
* Update the tests
* rename PartialExpression to Partial
* move Partial from expressions to types and rename to ArgumentPlaceholder
* add tests for ArgumentPlaceholder in babel-generator
* rename Partial to ArgumentPlaceholder
* update the tests
* remove alias from the type and undo changes in generated folder
* adds a nice error message
* better definition for the type
* auto-generated files
* update the conditional for allowPlaceholder message and tests

* change description
* clean up
* indent ArgumentPlaceholder entry and revert unwanted changes
* fix: strip type imports used in Enums and object types

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.

* Also update babel-parser.d.ts
* babel-types is* type checks accept null | undefiend as value TS type
* Use | null | undefined instead of any, make Flow type nullable
* Also change flow types of generated src
* Remove types on program exit in typescript transform
* Revert changes to typescript transform
* Correctly add visitors for param decorators
* Fix plugin for node 6
