Apply sliding transition for lock screen

The flow of changing lock screen is combined with Settings and SUW pages
together where their implementation are different, which causes the
page-to-page transition inconsistent. Sub-setting pages will apply
shared axis transition while SUW pages will keep the slide in/out
transition. In order to make these 2 types of page work together, we
intent to use slide in/out transition in the lock screen.
