Add Box::from_corners method (#6672)

# Objective This add a ctor to `Box` to aid the creation of non-centred boxes. The PR adopts @rezural's work on PR #3322, taking into account the feedback on that PR from @james7132. ## Solution `Box::from_corners()` creates a `Box` from two opposing corners and automatically determines the min and max extents to ensure that the `Box` is well-formed.
