configs: MemConfig, add QoSMemSinkCtrl support
QoSMemSinkInterface is a special case of memory interface type, similar
to SimpleMemory. It requires a QoSMemSinkCtrl where most model parameters
are exposed. By adding support in "config_mem", we allow configurations
with multiple QoSMemSinkCtrls to be centrally configured, particularly
interleaving parameters.
