UefiCpuPkg/SmmCpu: Add PcdSmmApPerfLogEnable control AP perf-logging
When a platform has lots of CPU cores/threads, perf-logging on every AP produces lots of records. When this multiplies with number of SMIs during post, the records are even more. So, this patch adds a new PCD PcdSmmApPerfLogEnable (default TRUE) to allow platform to turn off perf-logging on APs.
