Add sourceRootPath to the Project model

[pepicrft]

Short description 📝

Before this change, we used to pass down the sourceRootPath attribute to tell generators about the directory that contains the generated project. With the change in this PR that information is now part of the Project model.

But why? 🧐

This allows the mappers change the location where projects are generated. For example, let's say that users are using the new cache feature with the focus command. In that case, we don't want to override the projects that contain the targets with the source code. Instead, we want to create a temporary directory that contains all the Xcode projects with the direct and transitive dependencies as .xcframeworks.

Thanks @pepibumur - moving some of those properties to the Project model makes sense as it will allow transforming / mapping them on a per project basis 👍

I believe we'll need to also add xcodeProjPath to get the editor working as it did before 🤐 and support the proposed feature in general.

May help for us to write down what each of those paths represents:

• Project.path the logical path of the project within the graph
• Project.sourceRootPath the root path of the sources (Determines the path of the main group in Xcode)
• xcodeProjPath the physical location of the .xcodeproj file on disk

The main group in Xcode has a path that is:

let projectRelativePath = sourceRootPath.relative(to: xcodeprojPath.parentDirectory).pathString

Thanks for the review @kwridan. I followed your suggestions and made the following changes:

• Added xcodeProjPath attribute to Project and use it from the descriptor generator to get the path where the Xcode projects are generated.
• Removed fileName from Project and update the enriched method in GeneratorModelLoader that changes the project name based on the config. This makes me think we should move this into a mapper soon.
• Fixed the edit command to generate the project in the right directory.
• Remove the generation options model because it's no longer necessary.

Thanks for the updates @pepibumur - changes look 👍

minor: I believe this may need to be:

enrichedModel.xcodeProjPath.parentDirectory.appending(component: "\(xcodeFileName).xcodeproj")

Ouch, good catch.
