Move kTitleIconSize to class member (browser/ui)

When building using Jumbo unnamed namespaces gets merged
and variables with the same name conflict. This happens
for the variables kTitleIconSize in
views/ime/ime_window_frame_view.cc,
views/relaunch_notification/relaunch_recommended_bubble_view.cc
and views/relaunch_notification/relaunch_required_dialog_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.
