Render layers like layer.cutout=<blocks> in block.properties no longer working

There is a pull request for Iris that fixes the same bug. Maybe you can take it as a reference.

Steps to Reproduce

1. Try Sundial Lite which have set redstone wire type to cutout
2. See redstone wire still rendered as translucent

I think this is the same issue, glass and glass panes should be translucent as they are specified in block.properties on layer.translucent, however, seemingly only those 2 blocks, are not treated as they should be.

All the other blocks I've tried in Misa's texture pack which are specified in block.properties work as expected.

Take the stonecutter for example, the edges of that can only be translucent with the block specified in block.properties, so that's obviously working fine. Just the glass that doesn't. Possibly because it uses a custom model or CTM, though it worked fine in previous releases of OptiFine up to 1.21.11.

Resource packs no longer need layer.translucent or layer.cutout from 26.1. Now vanilla will make a certain face translucent if there is any semi transparent pixel, or using force_translucent for that texture in model files. Cutout faces will also be automatically converted if texture of this face contains full transparent pixel but no semi transparent pixels.

Ah, I thought that was a 26.2 thing.
In that case, what I've found is a CTM bug, as when translucent textures are added by CTM, the render type is not changed. Adding translucent pixels to the texture in /minecraft/textures/block has fixed the problem.
