Add new scriptlet — 'trusted-set-object-defineproperty'

[piquark6046]

Introduction

Since Netflix uses Object.defineProperty to define functions related to advertisement ¹, it seems that new scriptlet setting inbound and outbound of Object.defineProperty and Object.defineProperties is required for the advanced filtering quality.
Also, bundlers and transpilers like Babel often use Object.defineProperty to emulate certain ES6+ features in a way that's compatible with older JavaScript environments as GitHub Copilot said.

Proposed Syntax

example.org#%#//scriptlet('trusted-set-object-defineproperty', [NonFunctionalBoolean [, ReturnAs [, FilledWith [, stack]]]])

• NonFunctionalBoolean — Non-functional comparative text like Object.entries.name === 'entries'. _Inbound (inbound argument for the mocked functions) and _Outbound (Reflect.apply result of the object.defineproperty or object.defineproperties) should be revealed in the non-functional comparative text to compare.
• ReturnAs — Like value argument of set-constant scriptlet, a returned value instead of the actual outbound result.
• FilledWith — (boolean) If it is true and the actual outbound result is Object, all entries of the object will be filled with ReturnAs. Otherwise, FilledWith argument will be ignored.

Usage with no arguments will log inbound arguments and outbound result to browser console.
