MdeModulePkg/FPDT: Lock boot performance table address variable at EndOfDxeedk2-stable202111-rc1
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.
