Subject: SL-18190 Fix alpha not playing nice with water surface by split
 LLDrawPoolAlpha into two passes, one above water, one below water, and clip
 against water plane.  Currently brute forces two complete alpha passes, still
 need to cull against water plane and add support for fullbright shaders.
