Darbin Reyes fd1820b7ea UefiCpuPkg/MicrocodeMeasurementDxe: Fix exception
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4360

An incorrect format specifier is being used in a DEBUG print,
specifically, a variable of type EFI_STATUS was being printed with
the %a format specifier (pointer to an ASCII string), thus the value of
the Status variable was being treated as the address of a string,
leading to a CPU exception, when encountered this bug manifests itself
as a hang near "Ready to Boot Event", with the last DEBUG print being
"INFO: Got MicrocodePatchHob with microcode patches starting address"
followed by a CPU Exception dump.

Yang, Longlong 6612ff8561 UefiCpuPkg: Extend measurement of microcode patches to TPM
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3683

TCG specification says BIOS should extend measurement of microcode to TPM.
However, reference BIOS is not doing this. BIOS shall extend measurement of
microcode to TPM.
