SpeedTreeLib: port 40250 wrapper/forest verbatim over a CSpeedTreeRT stand-in

Delete the platform proxy tree renderer and copy SpeedTreeWrapper, SpeedTreeForest, SpeedTreeForestDirectX8, SpeedTreeConfig.h and VertexShaders.h from 40250. The SDK SpeedTreeRT.h public API becomes the shim; the closed CSpeedTreeRT is reimplemented in platform/SpeedTreeLib/SpeedTreeRT.cpp (procedural geometry, static lighting, single LOD, DIVERGENT). Shims gain the D3D8 vertex shader declaration tokens, D3D_OK, CreateVertexShader/DeleteVertexShader, ID3DXBuffer/D3DXAssembleShader, MessageBox and __min/__max.
