Fix the background color of CollapsingToolbarLayout

The wrong background color of CollapsingToolbarLayout appears in some
pages like "All apps" page or "Password and accounts" page. This symptom
can be observed in these pages when the work profile is enabled and the
line count of title is 1.

This issue is caused by updating the title of the page many times. In
these pages that have the tab view, the structure of the page differs
from a general setting page. The title of the page is coming from
BaseActivity, ProfileSelectFragment, PersonalFragment and WorkFragment,
in which the page that has the issue has an empty string from
ProfileSelectFragment. That is causing the CollapsingTollbarLayout has
the different line count during the process of setting the title.

Since the pages that have the tab view are different from the general
pages in Settings, the title should be set separately for those pages.
Adding a method to get the title resource ID so the page extending from
ProfileSelectFragment can set its title.

Test: visual test and manual test
