REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1366

Commit b3c71b472dff2c02f0cc38d7a1959cfb2ba8420d supported MSR setting
in different scopes. It added below macro:
 CPU_FEATURE_THREAD_BEFORE
 CPU_FEATURE_THREAD_AFTER
 CPU_FEATURE_CORE_BEFORE
 CPU_FEATURE_CORE_AFTER
 CPU_FEATURE_PACKAGE_BEFORE
 CPU_FEATURE_PACKAGE_AFTER

And it re-interpreted CPU_FEATURE_BEFORE as CPU_FEATURE_THREAD_BEFORE
and CPU_FEATURE_AFTER as CPU_FEATURE_THREAD_AFTER.

This patch retires CPU_FEATURE_BEFORE and CPU_FEATURE_AFTER
completely.
