This commit fixes the following regressions: 1. Transmission-specific calls to shader lighting functions didn't pass the `enable_diffuse` parameter, breaking the `transmission` example. 2. The combination of bindless `StandardMaterial` and bindless lightmaps caused us to blow past the 128 texture limit on M1/M2 chips in some cases, in particular the `depth_of_field` example. https://github.com/gfx-rs/wgpu/issues/3334 should fix this, but in the meantime this patch reduces the number of bindless lightmaps from 16 to 4 in order to stay under the limit. 3. The renderer was crashing on startup on Adreno 610 chips. This PR simply disables bindless on Adreno 610 and lower.
