igc: Add XDP hints kfuncs for RX hash
This implements XDP hints kfunc for RX-hash (xmo_rx_hash).
The HW rss hash type is handled via mapping table.
This igc driver (default config) does L3 hashing for UDP packets
(excludes UDP src/dest ports in hash calc). Meaning RSS hash type is
L3 based. Tested that the igc_rss_type_num for UDP is either
IGC_RSS_TYPE_HASH_IPV4 or IGC_RSS_TYPE_HASH_IPV6.
This patch also updates AF_XDP zero-copy function igc_clean_rx_irq_zc()
to use the xdp_buff wrapper struct igc_xdp_buff.
