[posix] add a flag to turn posix multicast routing feature on/off (#9412

) This commit adds a separate flag to be able to turn the posix part of multicast routing implementation off/on. The new OPENTHREAD_POSIX_CONFIG_BACKBONE_ROUTER_MULTICAST_ROUTING_ENABLE flag guards the feature of posix multicast routing using MFC(multicast forwarding cache) in MRT(multicast routing table). The existing OPENTHREAD_CONFIG_BACKBONE_ROUTER_MULTICAST_ROUTING_ENABLE continues to guard the core multicast routing feature, for example handling the MLR.req message and the multicast listeners table. In a system where it has its own multicast routing support for packet forwarding between Thread network and AIL, it should set OPENTHREAD_POSIX_CONFIG_BACKBONE_ROUTER_MULTICAST_ROUTING_ENABLE to 0.
