ice: add virtchnl definitions and static data for GTP RSS

Add virtchnl protocol header and field definitions for advanced RSS
configuration including GTPC, GTPU, L2TPv2, ECPRI, PPP, GRE, and IP
fragment headers.

- Define new virtchnl protocol header types
- Add RSS field selectors for tunnel protocols
- Extend static mapping arrays for protocol field matching
- Add L2TPv2 session ID and length+session ID field support

This provides the foundational definitions needed for VF RSS
configuration of tunnel protocols.
