net: ethernet: mediatek: Add metadata support for xdp mode
Set metadata size building the skb from xdp_buff in mediatek driver.
mtk_eth_soc driver sets xdp headroom to XDP_PACKET_HEADROOM so the
headroom is large enough to contain xdp_frame and xdp metadata.
Please note this patch is just compiled tested.
