Standing on structures such as crates, tables and bed will now look like it. (#79797)

## About The Pull Request
From the creator of 'cosmetic' elements such as footstep_override and
immerse...

I've made an element called elevation that nudges mobs a few pixels up
while standing on things like tables, crates and beds.

Screenshots of many clones of the same character standing on different
objects:

## Why It's Good For The Game
It makes it look like the mob is actually standing on an elevated
surface.
