> GN chrome/common build, rename enable_printing.
> 
> This adds the missing conditions to the chrome/common GN build file (previously
> only the basic files were there). Some refactoring of the GYP file to make this
> possible.
> 
> Renames the enable_printing flag to printing_mode since this is an integer
> tri-state.
> 
> Minor improvements to chrome/renderer
