Replace Existing Program/Rule Engine with eBPF

[nibanks]

Currently, XDP for Windows has a custom set of rules that can make up a "program" that an app pushes down to configure how packets should be handled. This custom logic isn't super performant, nor is it very configurable. This is a great opportunity to partner with https://github.com/microsoft/ebpf-for-windows and integrate with that instead of the custom logic currently supported.
