ShortcutHelper::InstallWebApkInBackgroundWithSkBitmap()
- To talk to WebAPK server (https://webapk.googleapis.com/v1alpha/webApks?alt=proto)
  to generate WebAPK
- To download WebAPK from URL returned by WebAPK server

This CL also:
- Adds stub for talking to Google Play client to install WebAPK
- Introduces manifest_util.h with methods for converting blink::WebDisplayMode
  and blink::WebScreenOrientationLockType to and from string
