krzysztof narkowicz f9d066a72a Lumen - SurfaceCache optimizations and cleanup ...

* Removed Opacity surface cache atlas layer (saves 8mb with compression and 16mb without). Also doesn�t need to be ever sampled in shaders
* Unified invalid texel handling. Instead of using depth and opacity, a single bit encoded in depth is used to decide whether a pixel is masked or not
* Unified surface cache encoding and decoding through FLumenSurfaceCacheData so that they are done in a single function and it�s easy to change surface cache encoding
* Moved surface cache shaders to a SurfaceCache folder
* Fixed surface cache reversed depth
