DxeSmmPerformanceLib previously is used by DP tool. But in new pweformance infrastructure, we have updated Dp tool to get the performance data from firmware performance data table in ACPI. Now the DxeSmmPerformanceLib is not used by any module. So remove it from edk2 code base to avoid being used by mistake.
