Move MiiData to its own namespace and add ChecksummedMiiData (#6824) 

* Move mii to own namespace and add checksummed mii data

* Fix compile issues

* Make mii classes trivial and add cast operator

* Fix Android side

* Add new line at the end of files.

* Make miidata a struct and crc16 a u32_be as per switch code.

* Apply suggestions

* Change back crc to u16 and set padding to 0.
