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

Browse Source 
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.
