First of a bunch of the cleanups suggested by
https://codereview.chromium.org/659883002/.

https://codereview.chromium.org/669213004/diff/1/ui/gfx/screen_win.cc
File ui/gfx/screen_win.cc (right):

https://codereview.chromium.org/669213004/diff/1/ui/gfx/screen_win.cc#newcode96
ui/gfx/screen_win.cc:96: bool ScreenWin::IsDIPEnabled() {
I think IsDIPEnabled could be deleted, it seems to be either NOTIMPLEMENTED or
return true everywhere. I'll do that subsequently.
