Cross models have one side with UV flipped on X but should NOT

> Summary:
Grass, Flowers, Saplings, Kelp plant are all using a specific hardcoded model which is basically 2 double sided faces crossed at 90° angle.
Problem is that one of the 2 faces has flipped UV, showing weird result on sides of those blocks, very noticeable on Kelp plants and with HD textures.

> Impact:
Wrong texture result, one side being flipped when not necessary (and unwanted)

> Repro Steps:
Compare Grass, Flowers, Sapplings, Kelp etc with Java Edition which doesn't have that bug.

> Observed results:
1 face of the cross model (hardcorded) has its texture flipped on X

> Expected results:
Cross model should not have any of its face flipped on X.
