Place static_assert() immediately after each of icssg_all_miig_stats[] and icssg_all_pa_stats[] in icssg_stats.h to verify at build time that ICSSG_NUM_MIIG_STATS and ICSSG_NUM_PA_STATS stay in sync with the actual array sizes. This turns a silent miscount into a build error should either the constant or the array be updated independently.
