Remove previous print preview work in preparation for new work.

The new work will take a very different approach (using a component extension,
similar to the bookmark manager).

This basically reverts the following commits:
- http://src.chromium.org/viewvc/chrome?view=rev&revision=20595
  (http://codereview.chromium.org/155067)
- http://src.chromium.org/viewvc/chrome?view=rev&revision=19918
  (http://codereview.chromium.org/155051)
- http://src.chromium.org/viewvc/chrome?view=rev&revision=19906
  (http://codereview.chromium.org/150207)

BUG=173
TEST=everything still builds

Review URL: http://codereview.chromium.org/2156003

git-svn-id: svn://svn.chromium.org/chrome/trunk/src@48162 0039d316-1c4b-4281-b951-d872f2087c98
