[Setup] Theme ChooseLockGeneric for setup wizard

This is step one of theming the set-up lock screen flow to match the
setup wizard theme. This shows the general approach of creating a
subclass of both the activity and fragment and overriding methods to
achieve the desired behavior for setup.

ag/594000 is a much more comprehensive change for what the final
change will look like.
