ice: add flow parsing for GTP and new protocol field support

Introduce new protocol header types and field sizes to support GTPU, GTPC
tunneling protocols.

- Add field size macros for GTP TEID, QFI, and other headers
- Extend ice_flow_field_info and enum definitions
- Update hash macros for new protocols
- Add support for IPv6 prefix matching and fragment headers

This patch lays the groundwork for enhanced RSS and flow classification
capabilities.
