Add static mark and animate mark

Like client component and server component.

```js
const root = cm.create("#root", {width: 200, height: 50});

root.render(sketch());
```
```js
function sketch() {
  return {
    loop: true,
    render: () => [
      cm.svg("circle", {
        cx: Math.abs(Math.sin(Date.now() / 1000) * 200),
        cy: 25,
        r: 20,
        stroke: "red",
        strokeWidth: 4,
      }),
    ],
  };
}
```
