Initial whack at getting ash_unittests to connect to a viewer process on Win/Metro.

This adds a test viewer process host to the ash unittests that starts and connects to the viewer process, using the provided hwnd as a backing surface for the tests.

This approach allows most of the ash unittests to pass except for two categories:
1) Tests that spin up more than one ash display. These don't work since each RootWindowHost thus created would require a remote connection and there is only one Metro viewer process.
2) Some number of tests seem to tickle a crash in shader.cc. These are short-circuited on Win8 with a TODO. 

Some limitations:
1) The tests require chrome.exe to be registered as the default browser on Windows 8 to be used as a viewer process. This could be fixed in a future CL by creating a minimal viewer process for tests.
2) To register chrome.exe as the default browser, setup.exe needs to be built and run with 
setup.exe --register-dev-chrome --register-dev-chrome-suffix=.test
This will be fixed in a future CL by extracting the registration code.

The interesting parts are in ash/test/test_metro_viewer_process_host.h
ash/test/test_metro_viewer_process_host.cc

Most of the rest is test disabling or calling the above.
