x86/resctrl: Add a new resource type RDT_RESOURCE_SMBA
Add a new resource type RDT_RESOURCE_SMBA to handle the QoS enforcement policies on the external slow memory. Mostly initialization of the essentials. Setting fflags to RFTYPE_RES_MB configures the SMBA resource to have the same resctrl files as the existing MBA resource. The SMBA resource has identical properties to the existing MBA resource. These properties will be enumerated in an upcoming change and exposed via resctrl because of this flag.
