M60: Print Preview: Disable Generate Draft feature.

The attempt to restore this feature in r469749 did not quite do the job
and has several issues.

This is not cherry-picked from the master branch because the related
test got rewritten.

Remove Print Preview's generate draft feature in the renderer.

The feature has lived on for too long in a broken state, and just makes
the code more complicated than necessary. Remove the rendering code
that deals with generating draft pages. There still exists browser side
code to be removed later.

This CL makes a PrintPreviewFailureType enum value obsolete. While
marking it as deprecated, also fix another issue with
PrintPreviewFailureType where the wrong enum got marked as deprecated.

It turns out this actually started a long time ago with r227717 and r236642. The original reason was that the generate draft feature only helped in 0.5% of the preview requests.
