With the new Turbofan variants (NCI and Turboprop), we need a way to distinguish between them both during and after compilation. We initially introduced CompilationTarget to track the variant during compilation, but decided to reuse the code kind as the canonical spot to store this information instead. Why? Because it is an established mechanism, already available in most of the necessary spots (inside the pipeline, on Code objects, in profiling traces). This CL removes CompilationTarget and adds a new NATIVE_CONTEXT_INDEPENDENT kind, plus helper functions to determine various things about a given code kind (e.g.: does this code kind deopt?). As a (very large) drive-by, refactor both Code::Kind and AbstractCode::Kind into a new CodeKind enum class.
