Add support for l3 mode in agent.

There are three forwarding modes at VN level and global level-
l2_l3(IRB), l3 only(v4+v6), l2 only.
VN level configuration is always at highest priority.
In case VN level forwarding mode is not configured then global
mode is consulted.

For multicast store the knowledge of bridging enabled in local peer path. This
helps in identifying if EVPN/TOR subscription/withdraw needs to be sent.
