UefiCpuPkg/Feature: Support different thread count per core
Today's code assumes every core contains the same number of threads.
It's not always TRUE for certain model.
Such assumption causes system hang when thread count per core
is different and there is core or package dependency between CPU
features (using CPU_FEATURE_CORE_BEFORE/AFTER,
CPU_FEATURE_PACKAGE_BEFORE/AFTER).
The change removes such assumption by calculating the actual thread
count per package and per core.
