Add Node-API utility scripts and configuration files.

- Introduced new tools for N-API module detection (`check-napi.js`), formatting using Clang and ESLint (`clang-format.js`, `eslint-format.js`), and source conversion (`conversion.js`).
- Added N-API-specific configuration files (`common.gypi`, `except.gypi`).
- Included N-API bindings and licensing files (`index.js`, `LICENSE.md`, `napi.h`).
