Sukchan Lee b47bad8b84 [HR] Implement GTP-U processing for HR Roaming in User Plane (#2194) ...

- Added support for the N9 For Roaming interface type:
  - Core interface act as V-UPF.
  - Access interface act as H-UPF.

- Modified V-UPF behavior:
  - V-UPF updates only the TEID and IP Address in the GTP-U header.
  - The content following the Extension Header is passed through directly
    between the UE and H-UPF.

This implementation ensures seamless data flow between the UE, V-UPF, and H-UPF
while maintaining integrity for Home Routed Roaming scenarios.
