Support SwiftPM warning-control build settings

Tuist now understands SwiftPM’s newer warning-control target build settings, including treatAllWarnings, treatWarning, and enableWarning. This means packages like swift-dependencies 1.13.0, which use these APIs, can be loaded and translated into Xcode projects without failing during package decoding. The generated Xcode projects preserve the package author’s warning behavior for supported Swift, C, and C++ settings.
