Remove ExtensionHost dependencies on file/color picker and browser_shutdown

* Move file and color picker support to ExtensionViewHost, because they can
  only be spawned by a click on a visible page element in a UI view.
* Set RenderProcessHostImpl fast_shutdown_started_ slightly earlier and use
  it to check for fast shutdown in ExtensionHost

This is part of the app_shell extensions refactor project.
