[bc25] Add an animated transition for `QuickSettingsShadeScene`.
This is a basic transition for the shade from both `Gone` and
`Lockscreen` scenes. Once a motion spec is available, this transition
will be revised and improved.
Test: Manually tested by opening and closing the quick settings shade on
a foldable device both in a folded and unfolded configuration.
Test: Unit tests build and pass.
