Inconsistency with item models for walls and fences

The item model for a fence is composed of two fence blocks connecting to each other. However, the item model for a wall is composed of a central post with two wall sections branching from it, which is not consistent with the similar fence. Either the fence should be changed to a central post, or the wall should have two posts.

This is also a parity issue, as Bedrock Edition uses a wall model with two posts.

A fixed model which switches the fence item to be a single post (UV-accurate) is attached.
