Add SignedExchange related DevTools layout tests

We are trying to show SignedExchange related information in DevTools.
https://bit.ly/2HXVbCU

This CL adds LayoutTests and -expected.txt files to track the progress
of the implementation.

Currently there are some difference from the ideal behavior:
- The status code of the succeeded .htxg should be 200. Currenly it is
  302 which is the status code of internally generated redirect
  response.
- The status code of the invalid .htxg should be 200. Currenly it is 0
  because the actual response is not sent to DevTools. DevTools just
  recieves "loadingFailed" event.
- The request to the certificate file shold be displayed. Currenly
  DevTools doesn't recieve the certificate request which is sent from
  the browser process.
- There is no signed exchange related information in the network log.
