0024310: TKOpenGl - GLSL compatibility issues

Lights defintion clean up:
- remove duplicated enumeration TLightType (equals to Visual3d_TypeOfLightSource)
- remove unused fields from Graphic3d_CLight
- OpenGl_Light, reuse Graphic3d_CLight definition

Phong GLSL program:
- move out cumulative ambient light intencity from limited list of lights
- compatibility issues, replace array of structures (light sources, materials, clipping planes) with arrays of primitive types

New Draw Harness command vlight to alter light sources definition.

OpenGl_ShaderProgram::Initialize() - add missing Linker log
