This change adds the pring preview part of the new print UX. The
UI has two parts, the top section is the print options and the
bottom section print preview with a list of pages. The user can
interact only with one of them. When print options are expanded
they cover the preview content and a scrim is laid out on top of
the preview. Tapping the scrim collapses the print options. When
the user types in page ranges and closes the options to look at
the preview, the latter is updated to show only these pages. In
the list of pages the user can further prune pages by deselecting
them.

1. We were using the layout for the printer drop down from the
print dialog as the list item in the all printers activity.
This layout was not high enough. Now we have a separate
layout for the drop down and for the list. Note that they
are almost identical but this is better that writing java
code to lookup the height from the theme and change it
programatically since the java code is almost half the size
of the layout and leads to spreading the logic in both the
layout file and the java code.
2. The padding of the printers list was not correct. Now it
mimics the bahavior in settings where we change the padding
based on orientation.
