ice: Support RX hash XDP hint
RX hash XDP hint requests both hash value and type. Type is XDP-specific, so we need a separate way to map these values to the hardware ptypes, so create a lookup table. Instead of creating a new long list, reuse contents of ice_decode_rx_desc_ptype[] through preprocessor. Current hash type enum does not contain ICMP packet type, but ice devices support it, so also add a new type into core code. Then use previously refactored code and create a function that allows XDP code to read RX hash.
