To Support Antrea Host Network Policy about antrea

This is a duplicate of #4213, so please close one of them

@antoninbas ,
It is created to track additional use-cases related to Antrea Host network policy, apart from the use case which is mentioned in scope of #4213 , In 4213, we will not be supporting multiple interfaces use-case and few other use-cases.

@rajnkamr it seems the use cases mentioned in the issue is not very different from 4213. "To handle non IP Packet in datapath" doesn't seem a valid requirement, I don't know in which case users want to use NetworkPolicy to manage non IP packets.
Please also note that the proposal I made in #4213 (comment) didn't get agreement in the community meeting. So if your proposal is based on it, please consider the mentioned risks and complexity. I want to also mention that we are reconsidering other approaches that are less disruptive. To avoid duplicate efforts, please discuss your proposal first before making code change.

@tnqn
With non ip packet i meant packets which are not destined for pod network, for example for Host-level communication the node on which Antrea is running is a regular host in the network. As such, it may still receive and process non-IP packets destined for the node itself, unrelated to pod networking.
also the underlying network infrastructure that connects the nodes may carry non-IP traffic. For example, communication between network switches, routing protocols, or other specialized networking functions might utilize non-IP packets.

Although this issue is created based on #4213 proposal, we might not want to cover all use-cases under 4213,
Currently, proposal is in discussion only and demo solution is only partially ready, we will have design and final proposal discussion before going for final implementation.
