ice: detect and report PTP timestamp issues

Jacob Keller says:

This series fixes a few small issues with the cached PTP Hardware Clock
timestamp used for timestamp extension. It also introduces extra checks to
help detect issues with this logic, such as if the cached timestamp is not
updated within the 2 second window.

This introduces a few statistics similar to the ones already available in
other Intel drivers, including tx_hwtstamp_skipped and tx_hwtstamp_timeouts.

It is intended to aid in debugging issues we're seeing with some setups
which might be related to incorrect cached timestamp values.
