mlxsw: spectrum_router: Refactor virtual router handling

A virtual router (VR) is an entity within the device to which routing
tables and interfaces can be bound to. It can be used to implement VRFs.

In the initial implementation we associated the VR with a specific
protocol (e.g., IPv4) and an LPM tree. However, this isn't really
accurate, as the same VR can be used for both IPv4 and IPv6 traffic, by
binding a different LPM tree to a {VR, Proto} pair.

This patch aims to restructure the VR code according to the above logic,
so that VRs are more accurately represented by the driver's data
structures. The main motivation behind this change is to prepare the
driver for VRF offload.
