x86/resctrl: Update documentation with Sub-NUMA cluster changes
With Sub-NUMA Cluster (SNC) mode enabled, the scope of monitoring resources
is per-NODE instead of per-L3 cache. Backwards compatibility is maintained
by providing files in the mon_L3_XX directories that sum event counts
for all SNC nodes sharing an L3 cache.
New files provide per-SNC node event counts.
Users should be aware that SNC mode also affects the amount of L3 cache
available for allocation within each SNC node.
