Pig saddle is not on the same layer as the cold pig's wool

Steps to Reproduce:

1. Enable the Drop 1 2025 experimental toggle
2. Find or spawn a cold pig
3. Equip it with a saddle
4. Look closely

Observed Results:
The saddle is slightly more inflated than the pig's outer body layer instead of being merged into the texture like in Java Edition.

Expected Results:
The saddle is on the same layer as the pig's outer body layer, matching Java Edition.

Screenshots/Videos attached: Yes

Notes: This is caused by the fact that saddles were turned into attachables instead of being part of the pig render controllers. I have attached a resource pack that fixes this issue in a simple and clean way.
