refactor(Polygon): rewrite with enhanceElement and cleaner interfaces

BREAKING CHANGE: Naming convention for event handlers has tweaked to follow React's convention.

Before:

```js
<Polygon
  onClick={_.noop}
  onRightclick={_.noop}
  onDragstart={_.noop}
/>
```

After:

```js
<Polygon
  onClick={_.noop}
  onRightClick={_.noop}
  onDragStart={_.noop}
/>
```
