Remove nonstandard Promise.prototype.done implementation

Summary:
Changelog:
[General][Breaking] - Remove nonstandard Promise.prototype.done

`Promise.prototype.done` has been deprecated since D34222667. Here we remove it from React Native's default Promise polyfill. Users should switch to using standard Promise features like `.then()`, or install their own custom polyfills for advanced use cases.
