Haoyu Qiu 5183c473f7 Backport new methods for KinematicBody and KinematicCollision
For both 2D and 3D, three methods are added:

- `get_floor_angle` on `KinematicBody` to get the floor angle.
- `get_angle` on `KinematicCollision` to get the collision angle.
- `get_last_slide_collision` to quickly get the latest collision of `move_and_slide`.
