connected glass/ctm support for bedrock

add connected texture support for glass so blocks visually merge. it should also work with resource packs from the marketplace. glass right now looks like an excel sheet. a lot of players already try to fix this with packs, but bedrock doesn’t support it properly. java already has ways to do this. let adjacent glass remove internal borders while keeping outer edges. Ideally works with both default textures and resource packs. could make it a toggle for flexibility
