In order to support more coalesce parameters through netlink,
add an new structure kernel_ethtool_coalesce, and keep
struct ethtool_coalesce as the base(legacy) part, then the
new parameter can be added into struct kernel_ethtool_coalesce.

Also add new extack parameter for .set_coalesce and .get_coalesce
then some extra info can return to user with the netlink API.

This and the following patches don't build, please make sure
allmodconfig builds correctly. Here's an example failure, but
IDK if there isn't more:
