Fix applied rotation from moving platforms in move_and_slide

When synchronizing CharacterBody motion with moving the platform using
direct body state, only the linear velocity was taken into account.

This change exposes velocity at local point in direct body state and
uses it in move_and_slide to get the proper velocity that includes
rotations.
