Global style keyframes injection

[peduarte]

Fixes #185

This PR:

• ensures that css.global are server rendered
• ensures that css.keyframes are server rendered

Breaking change:
In order to be able to inject global styles, we need to make that a function.

const globalStyles = css.global({})

// call it
globalStyles()

in React

const globalStyles = css.global({})

const App = () => {
  // call here
  globalStyles()

  return <div/>
}

We could provide a nicer API, maybe a hook, in @stitches/react
