Support Xcode16's new synchronized folder format
It is not fully supported yet (supporting it requires changes to the tuist/XcodeProj code, which is in progress separately), but I belive it covers most cases.
Initially, I considered migrating to XcodeGraph following the flow of https://github.com/tuist/XcodeProj/issues/880, but due to operational issues and the need for many fixes, I decided to limit the changes to the existing codebase.
