net: bridge: multicast: make tracked EHT hosts limit configurable

Add two new port attributes which make EHT hosts limit configurable and export the current number of tracked EHT hosts: - IFLA_BRPORT_MCAST_EHT_HOSTS_LIMIT: configure/retrieve current limit - IFLA_BRPORT_MCAST_EHT_HOSTS_CNT: current number of tracked hosts Setting IFLA_BRPORT_MCAST_EHT_HOSTS_LIMIT to 0 is currently not allowed. Note that we have to increase RTNL_SLAVE_MAX_TYPE to 38 minimum, I've increased it to 40 to have space for two more future entries. v2: move br_multicast_eht_set_hosts_limit() to br_multicast_eht.c, no functional change
