Clang does not accept `-x objective-c` with WebAssembly target and it crashes with "Objective-C support is unimplemented for object file format" for now. `-enable-objc-interop` can work without the objc runtime support (which is indicated by `objc_interop` feature), so this adds a new `objc_codegen` feature to require Objective-C support only at compile-time.
