ice: Support HW timestamp hint
Use previously refactored code and create a function
that allows XDP code to read HW timestamp.
Also, introduce packet context, where hints-related data will be stored.
ice_xdp_buff contains only a pointer to this structure, to avoid copying it
in ZC mode later in the series.
HW timestamp is the first supported hint in the driver,
so also add xdp_metadata_ops.
