LibGL: Implement glPolygonMode
Currently just sets the renderer option for what polygon mode we want the rasterizer to draw in. GLQuake only uses `GL_FRONT_AND_BACK` with `GL_FILL` )which implies both back and front facing triangles are to be filled completely by the rasterizer), so keeping this as a small stub is perfectly fine for now.
