Summary:
I wanna repeat the constants export in `yoga-wasm-web`, to achieve
```js
import { ALIGN_CENTER } from "yoga-layout";
```
And I failed. it is impossible because `rollup` and other tools can't transform commonjs `module.exports = { WHATEVER: 1 }` into ECMAScript modules. however, they can work with separate exports like `exports.WHATEVER = 1` and this PR transforms yoga constants into this convertible format
This doesn't change anything for the yoga package, but it makes it possible to reexport constants without any modification and hacks, like this
```js
export * from "./javascript/src_js/generated/YGEnums.js";
```
