Wildcard attach for XDP eBPF programs (ifIndex = 0)

[saxena-anurag]

xdp-for-windows currently does not support wildcard attach of eBPF programs. Wildcard attach happens when user provides ifIndex = 0. In this case the eBPF program is attached to all the interfaces.

Context: XDP hook implementation in ebpf-for-windows repo supports wildcard attach of programs.
