Support es modules (#1583)

Browse Source 
Ref https://github.com/svg/svgo/issues/1579

In config of course. Projects with type:module can now use modules to
export config

```js
export default {
  plugins: []
}
```

Also added support for resolving svgo.config.mjs and svgo.config.cjs.

Moved loadConfig tests to svgo-node tests.

mjs test is skipped for now in node 10, just don't use modules there
