net/ice/base: refactor RSS configure API

Use struct ice_rss_hash_cfg as parameter for
ice_add_rss_cfg, ice_add_rss_cfg_sync and
ice_rem_rss_cfg, ice_rem_rss_cfg_sync.

Introduce enmu ice_rss_cfg_hdr_type to allow user specify the more
flexible RSS configure.

ICE_RSS_OUTER_HEADERS - take outer layer as RSS inputset
ICE_RSS_INNER_HEADERS - take inner layer as RSS inputset
ICE_RSS_INNER_HEADERS_W_OUTER_IPV4
	- take inner layer as RSS inputset for packet with outer IPV4
ICE_RSS_INNER_HEADERS_W_OUTER_IPV6
	- take inner layer as RSS inputset for packet with outer IPV6
ICE_RSS_ANY_HEADERS - try with outer first then inner
		(same as the behaviour without this change)
