World lighting fixes

* Add channel selection for roughness and metallic textures
  * This lets u combine roughness & metallic into one texture
* Add Bakery-compatible emission slot
* Add compile-time toggle for brightness clamping
* Add toggle for world interpolators
* Add emission type dropdown (baked/realtime/none)
* Switch to bilinear filtering for base PBR maps to match standard
  shader behavior
* Add bugfixes for Mochie BRDF in world lighting mode
* Rename _NormalTex to _BumpMap for compatibility with standard shader
* World lighting mode uses Unity baked GI logic instead of normal world
  lighting logic
* Use uv2 instead of lmuv for lightmap UVs
