MdeModulePkg/SmmCorePerformanceLib: Disable perf-logging at runtime
Because SMM perf-logging is migrated to non-SMRAM at ReadyToBoot
by DxeCorePerformanceLib, the perf-logging after ExitBS is useless and
impact the SMI latency at runtime.
Hence the SmmCorePerformanceLib is updated to disable perf-logging
after ExitBS.
