Emit an error if -Z instrument-xray is not supported
This is somewhat important because LLVM enables the pass based on target architecture, but support by the target OS also matters. For example, XRay attributes are processed by codegen for macOS targets, but Apple linker fails to process relocations in XRay data sections, so the feature as a whole is not supported there for the time being.
