[PhysicsServer, Box2DDirectSpaceState], Missing implementation for helper functions

[Ughuuu]

There are some helper functions that don't use the world direct, but only query collision, etc:

From PhysicsServer:

_shape_collide

From DirectSpaceState:

_intersect_ray
_intersect_point
_intersect_shape
_cast_motion
_collide_shape
_rest_info

[Ughuuu]

#5 Addresses a few of these(ray and point) but not fully. They still need a propert implementation, mainly problem is for Object* hack that godot-jolt also had.
This issue godotengine/godot-cpp#1066. Can be fixed though, it's just a matter of casting object correctly and testing.

These are not touched:

_intersect_shape
_cast_motion
_collide_shape
_rest_info
