[renderblocking] Add a WPT about a specific render-blocking use case

There is a specific use case of render-blocking web font:

• Font provider provides an external stylesheet with @font-face
  definitions
• The stylesheet has a link header that preloads font file with
  blocking=render

In this way, web developers can make a 3rd-party web font render-blocking
without the need to know (and maintain) the exact url of the font file.

This patch adds a WPT for this use case.
