Revert 132856 - Aura/ash split: Remove hacks and get chrome linking without ash.

views_unittests failure on Linux Chromeos.

For the first time now, you can do:

    > build/gyp_chromium -Duse_aura=1 -Duse_ash=0

And get a running chrome. It has lots of issues, especially related to
window placement, tab handling, etc, but it pops up and renders web content.

Also consolidates most of the desktop behavior into its own class.

Also makes views_examples_exe work again. Several of the hacks are no longer
needed after Ben's refactoring to support WebView.
