Move constants from namespace to class (browser/ui)

When building using Jumbo unnamed namespaces gets merged
and variables with the same name conflict. This happens
for the variables kStartPadding and kEndPadding in
chrome/browser/ui/views/download/download_item_view.cc
and chrome/browser/ui/views/download/download_shelf_view.cc.

This commit solves the issue by moving the variables from
the namespace to the class. It also moves other variables
in the same namespace, to keep the files locally consistent.
