refactor(es/helpers): Remove unnecessary exports (#9225)
**Description:**

Helper methods were exporting twice, `_` and it's own function name.
We can map the build script to export `_` as it's own name (filename).
Therefore we export only once as `_`, and map the name on the build
script.

```js
// helpers/_foo.js

function _foo() {
  // ...
}

export { _foo as _ }
```
```js
// index.js

// We know the func name will be `_foo` based on the filename.
export { _ as _foo } from '_foo.js'
```

Closes #9203
