For memory bandwidth monitoring on a memory-side MSC the domain id is a NUMA node id, so labelling those directories with the resource name ("MB") is misleading about what the id means. Add the RESCTRL_NODE monitor scope and a mon_domain_name() helper that returns "NODE" for node-scoped resources (and the resource name for all other scopes), then use it when building and removing monitor domain directories. Node-scoped monitor domains are now named mon_NODE_, making it clear the id is a NUMA node id. L3 and telemetry naming (mon_L3_, mon_PERF_PKG_) is unchanged.
