Separate project init and setup code to its own project

[glm4]

Ideally, the initial configuration, env keys setup and other processes needed in the future, should live in its own repository and Xcode project.

• This avoids polluting the ios-base repository
• Could be reused in different projects without needing to copy source files and scripts.
• Can be maintained easily and new features can be added just once.
• Could be distributed via SPM
