0032779: Visualization, TKOpenGl - support using a wide color window buffer format (10bit per component / 30bit RGB)

Added new flag OpenGl_Caps::buffersDeepColor disabled by default.
OpenGl_Window now tries to find a RGB10_A2 pixel format using wglChoosePixelFormatARB().
OpenGl_TextureFormat::FindSizedFormat() - added handling of GL_RGB10_A2 internal format.
OpenGl_View::SetWindow() now selects preferred FBO color format basing on parameters.
OpenGl_Context::DiagnosticInformation()/OpenGl_View::DiagnosticInformation() now include
information about window pixel format / FBO texture format.
