Summary [GTK] Use three buffers for DMA-BUF renderer

Two buffers is not enough, because we might be rendering in the UI process with the buffer that is being used by the web process. The first time we render a frame in the UI process we notify the web process that the buffer has been painted and web process does a swap and starts rendering the next frame. If there's a web view redraw before the next frame message is received in the UI process we would be using the current web process back buffer to repaint.
