Check lower 24 bits of ProcessorNumber instead of
the value of ProcessorNumber in the API
MpInitLibGetProcessorInfo() of MpInitLibUp instance.
Lower 24 bits of ProcessorNumber contains the actual
processor number.
The BIT24 of input ProcessorNumber might be set to
indicate if the EXTENDED_PROCESSOR

I suggest we explicitly use BIT24 instead of CPU_V2_EXTENDED_TOPOLOGY.
Using BIT24 clearly tells that processor
