Remove unneeded print APIs and update the min margins APIs.

1. Removed unneeded code in Resolution that was storing its
   label as resource and package name. We do not have predefined
   resolutions, therefore we always persist the label.

2. Renamed the print attribute margins to minMargins to reflect
   that these are the minimal margins the printer support. Updated
   the docs as well.

3. Renamed the create method of all builder to build.
