Revert of Repurpose views+content example into a generic multiprocess views runtime

Revert of Repurpose views+content example into a generic multiprocess views runtime (https://codereview.chromium.org/284113011/)

Reason for revert:
Broke Blink runhooks step http://build.chromium.org/p/chromium.webkit/builders/WebKit%20Win%20x64%20Builder%20%28dbg%29/builds/12039

Original issue's description:
> Repurpose views+content example into a generic multiprocess views runtime
> 
> This is to facilitate the addition of an app launcher example/demo app,
> separate from the browser, and to assist testing of the out-of-process
> compositor on mac.
> 
> The change splits out from the current views_examples_with_content_exe
> target a new views_content_client target placed in
> ui/views_content_client. views_examples_with_content_exe is updated to
> use it.
> 
> This will allow the app launcher to have its own example app, while
> reusing the logic to set up the multiprocess runtime environment for
> using views and content.
> 
> Follow-up patches for the views_content_client runtime will: isolate
> aura dependencies, introduce the gpu_process UI compositor, and
> implement the runtime environment for mac.
