UefiCpuPkg/MpService: GetProcessorInfo returns 6-level topology 

Intel SDM introduces 6-levels for describing the CPU topology:
* Package
* Module
* Tile
* Die
* Core
* Thread

A PI spec ECR was submitted to enhance CPU_MP PPI/Protocol to
support returning such information through GetProcessorInfo().
An accordingly change was implemented and pushed to edk2-staging.

Now the PI spec has been published.
The patch is cherry-picked from edk2-staging to edk2.
