Thread the static build configuration (formed from language options) in to the macro plugin handler, which will serialize it for use in the macro implementation. test this with a simple macro that checks whether a particular custom configuration (set via `-D`) is enabled or not. This required some re-layering, sinking the logic for building a StaticBuildConfiguration from language options down into a new swiftBasicSwift library, which sits on top of the C++ swiftBasic and provides Swift functionality for it. That can be used by the C++ swiftAST to cache the StaticBuildConfiguration on the ASTContext, making it available for other parts of ASTGen.
