bridge: vlan: add global mcast_query_response_interval option 

Add control and dump support for the global mcast_query_response_interval
option which sets the Max Response Time/Maximum Response Delay for IGMP/MLD
queries sent by the bridge. To be consistent with the same bridge-wide
option the value is reported with USER_HZ granularity and the same
granularity is expected when setting it.
Syntax:
 $ bridge vlan global set dev bridge vid 1 mcast_query_response_interval 13000
