* napi procedural macro for basic rust/JavaScript types * introduce the `compat-mode` for `napi` and `napi-derive` crates for backward compatible * remove #[inline] and let compiler to decide the inline behavior * cli now can produce the `.d.ts` file for native binding * many tests and example for the new procedural macro Co-authored-by: LongYinan <lynweklm@gmail.com>
