idpf: add HW timestamping statistics

Add HW timestamping statistics support - through implementing get_ts_stats.
Timestamp statistics include correctly timestamped packets, discarded,
skipped and flushed during PTP release.

Most of the stats are collected per vport, only requests skipped due to
lack of free latch index are collected per Tx queue.

Statistics can be obtained using kernel ethtool since version 6.10
with:
ethtool -I -T <interface>

The output will include:
Statistics:
  tx_pkts: 15
  tx_lost: 0
  tx_err: 0
