Implement preset-default plugin (#1513)
I saw complaints about `extendDefaultPlugins` api

- it cannot be used when svgo is installed globally
- it requires svgo to be installed when using svgo-loader or svgo-jsx
- it prevents using serializable config formats like json

In this diff I introduced the new plugin which is a bundle of all
default plugins.

```js
module.exports = {
  plugins: [
    'preset_default',
    // or
    {
      name: 'preset_default',
      floatPrecision: 4,
      overrides: {
        convertPathData: {
          applyTransforms: false
        }
      }
    }
  ]
}
```
