Rename kSeparatorWidth to be unique (browser/ui)

When building using Jumbo unnamed namespaces gets merged
and variables with the same name conflict. This happens
for the variables kSeparatorWidth in:
chrome/browser/ui/views/bookmarks/bookmark_bar_view.cc
chrome/browser/ui/views/location_bar/icon_label_bubble_view.cc

This commit solves the issue by renaming the constants to
something more file specific. It also renames other variables
in the same namespace, so the naming is locally consistent.
