OpenGL: fix color logic op

GL_LOGIC_OP is a synonym for GL_INDEX_LOGIC_OP, from OpenGL 1.0's indexed color drawing. It's not part of modern GL and causes an error in core profile.

GL_COLOR_LOGIC_OP is still supported in the latest GL. It's the last stage before writing to the framebuffer.

Part of T51164
