Disable preference change animations

This change affects the Clear Browsing Data and Passwords settings
screens, removing the default preference item animations.

These animations would occur on preference changes, and were
unintentionally introduced with the migration to Support Library
preferences, which are contained in a RecyclerView with default item
animations. Because these settings screens had preference changes occur
quickly (but asynchronously) as the fragment loaded, the animations
appeared janky.
