Chen A Chen b6f67b4d58 UefiCpuPkg/Microcode: Fix incorrect checksum issue for extended table
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1020

The following Microcode payload format is define in SDM spec.
Payload: |MicrocodeHeader|MicrocodeBinary|ExtendedHeader|ExtendedTable|.
When we verify the CheckSum32 with ExtendedTable, we should use the fields
of ExtendedTable to replace corresponding fields in MicrocodeHeader,
and then calculate the CheckSum32 with MicrocodeHeader+MicrocodeBinary.
This patch already verified on ICL platform.
