### Godot version

4.0 beta 10

### System information

Windows 10, NVidia 2070, Vulkan Mobile

### Issue description

A human-sized (0.4 x 1.8 x 0.4) CapsuleShape3D on top of a large (50 x 50 x 50) SphereShape3D produces unstable normals when performing a move_and_collide down.

In discussions on the physics channel of the Godot Contributors Chat, the SAT solver isn't a good choice when the exact collision information can be solved analytically.

The problem with the SAT solver is that it ends up producing two collision points A and B on the two colliding shapes, and then the vector between them is used to build the normal. The problem is that A and B end up being extremely close (1e-4 distance), so normalizing the vector results in a large amplification of any numeric errors.

The current API for the ```_collision_<shape1>_<shape2>()``` functions can only report their findings via the ```_CollectorCallback``` API, and that only allows for providing the A and B points. Instead the collision functions should also have a means of providing exact analytic collision information if available.

### Steps to reproduce

Construct a scene consisting of a large 50m sphere with a capsule shape resting on top of it. Then perform a move_and_collide down and print the collision normal vector.

This demo walks a capsule around the top of a large sphere drawing the normal vector. The vector flickers between the correct normal and weird unstable normals:
