IAP for iOS in Godot 4.x

[ultramarinebicycle]

Describe the project you are working on

A mobile game that I want to export to Apple platforms, specifically iOS.

Describe the problem or limitation you are having in your project

No first-party solution exists for implementing IAP on iOS.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Create a library/plugin that helps users create and test IAP, along with step-by-step documentation.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

Essentially the same way as for Godot 3.x. And also show common pitfalls.

If this enhancement will not be used often, can it be worked around with a few lines of script?

Not to the best of my knowledge.

Is there a reason why this should be core and not an add-on in the asset library?

In-app purchases are pretty much a fundamental requirement in modern game development.

Thanks for the proposal! Consolidating in godotengine/godot-ios-plugins#47, as update requests don't need proposals.
