On Windows ASH ensure that we get the display created for the root window serving ASH.

This name is confusing and implies we have a separate process that ash lives in,
which isn't the case. Maybe IsViewerProcess? Also, if you only need this in
window_sizer, how about moving there? Ideally the code you're changing would
exist only in window_sizer_ash.

IsViewerProcess does not seem right. Viewer is the process which runs on the
other side for Windows ASH. 

In any case, removed this function and replaced the call in window_sizer.cc with
a check for the switch there.

We can add a function for the same if we need similar functionality elsewhere
later.
