In settings we weren't properly taking into account battery saver
enabled dark theme. This CL makes it so that when battery saver
on we disable the toggle until battery saver is off since
you can't change dark theme in battery saver. Additionally it
adds a message indicating why the toggle was disabled so the
user doesn't get confused.

The dark theme screen has been removed in favor of a simple
toggle with a dialog that shows up the first time a user
tries to enable dark theme when in light theme.

The dark theme preference should have it's own screen rather than
being a dialog. This adds some boilerplate code that will be
needed for the illustration as well as converting the current
list preference to open a new screen.

Having consistent import order will reduce chance of merge
conflict between internal and external master
