MdeModulePkg/FPDT: Lock boot performance table address variable at EndOfDxe 

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2957

1. Allocate performance data table at EndOfDxe and then lock the varible
   which store the table address at EndOfDxe.

2. Enlarge PCD gEfiMdeModulePkgTokenSpaceGuid.PcdExtFpdtBootRecordPadSize
   from 0x20000 to 0x30000 in order to hold the Delta performance data
   between EndOfDxe and ReadyToBoot.

3. SMM performance data is collected by DXE modules through SMM communication
   at ReadyToBoot before.
   Now to do SMM communication twice, one for allocating the performance
   size at EndOfDxe, another is at ReadyToBoot to get SMM performance data.

4. Make SmmCorePerformanceLib rather than FirmwarePerformanceSmm to communicate
   with DxeCorePerformanceLib for SMM performance data and size.
