[PATCH v2 6/8] MdeModulePkg/FirmwarePerfDxe:Enhance for new pref infrastructure

[Dandan Bi <dandan.bi@intel.com>]

V2:
Update FirmwarePerformanceDxe to receive the address
of performance records instead of records content.

1. Remove the macro EXTENSION_RECORD_SIZE, since the extension
size can be got through PcdExtFpdtBootRecordPadSize.

2. Hook EFI_SW_DXE_BS_PC_READY_TO_BOOT_EVENT to install ACPI table

3. Copy SMM record accord to the allocated size

4. Receive Boot performance table address instead of
 contents which are reported DxeCorePerformanceLib.
