Change the render to be renderToStaticMarkup. [3pt]

This is part of the AMP feature. For full context please check out the final Implementation proposal.

---

The Google AMP framework doesn't need the custom data- attributes added by React, so instead of using renderToString, the @frontity/amp package needs to make Frontity use renderToStaticMarkup.

This can be done with a beforeSSR function. It'll be necessary to create a separate server.js file because we don't want to add react-dom/server to the client bundle.

// packages/amp/src/server.js
import { renderToStaticMarkup } from "react-dom/server";

export default {
  actions: {
    amp: {
      beforeSSR: ({ libraries }) => {
        libraries.frontity.render = renderToStaticMarkup;
      },
    },
  },
};

It needs the render function to be exposed in libraries.frontity.

Blocked until #685 and #557 are finished.

This issue wasn't closed automatically after merging the linked Pull Request because we merged it in a branch different than dev, so I'm closing this manually.
