ethtool: Add support for 800Gbps link modes

Add support for 800Gbps speed, link modes of 100Gbps per lane. As mentioned in slide 21 in IEEE documentation [1], all adopted 802.3df copper and optical PMDs baselines using 100G/lane will be supported. Add the relevant PMDs which are mentioned in slide 5 in IEEE documentation [1] and were approved on 10-2022 [2]: BP - KR8 Cu Cable - CR8 MMF 50m - VR8 MMF 100m - SR8 SMF 500m - DR8 SMF 2km - DR8-2 [1]: https://www.ieee802.org/3/df/public/22_10/22_1004/shrikhande_3df_01a_221004.pdf [2]: https://ieee802.org/3/df/KeyMotions_3df_221005.pdf
