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

Browse Source 
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.
