feat: move css to different package for size reduction (#2168)

PR based on https://github.com/software-mansion/react-native-svg/pull/1452 extracting `css` related components to different package to reduce the size of the package.

***THIS IS A BREAKING CHANGE***. From now on, you should import 
```
  SvgCss,
  SvgCssUri,
  SvgWithCss,
  SvgWithCssUri,
  inlineStyles,
  LocalSvg,
  WithLocalSvg,
  loadLocalRawResource,
  ```
 from `react-native-svg/css` package instead.
