The logic is similar to idpf_rx_hwtstamp, but the data is exported
as a BPF kfunc instead of appended to an skb to support grabbing
timestamps in xsk packets.

A idpf_queue_has(PTP, rxq) condition is added to check the queue
supports PTP similar to idpf_rx_process_skb_fields.

Tested using an xsk connection and checking xdp timestamps are
retreivable in received packets.
