ice: add tracking of good transmit timestamps
As a pre-requisite to implementing timestamp statistics, start tracking
successful PTP timestamps. There already existed a trace event, but
add a counter as well so it can be displayed by the next patch.
Good count is a u64 as it is much more likely to be incremented. The
existing error stats are all u32 as before, and are less likely so will
wrap less.
