This file implements all APIs in Performance Library class in MdePkg. It creates
performance logging GUIDed HOB on the first performance logging and then logs the
performance data to the GUIDed HOB. Due to the limitation of temporary RAM, the maximum
number of performance logging entry is specified by PcdMaxPeiPerformanceLogEntries.
number of performance logging entry is specified by PcdMaxPeiPerformanceLogEntries or
