rust: add utility procedural macro crate This commit adds a helper crate library, qemu-api-macros for derive (and other procedural) macros to be used along qemu-api. It needs to be a separate library because in Rust, procedural macros, or macros that can generate arbitrary code, need to be special separate compilation units. Only one macro is introduced in this patch, #[derive(Object)]. It generates a constructor to register a QOM TypeInfo on init and it must be used on types that implement qemu_api::definitions::ObjectImpl trait.
