Implement Neg for Direction2d and Direction3d (#11179)

Browse Source 
# Objective

I frequently encounter cases where I need to get the opposite direction.
This currently requires something like
`Direction2d::from_normalized(-*direction)`, which is very inconvenient.

## Solution

Implement `Neg` for `Direction2d` and `Direction3d`.
