UefiCpuPkg: Refactor initialization of CPU features during S3 resume 

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3621
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3631

Refactor initialization of CPU features during S3 resume.

In addition, the macro ACPI_CPU_DATA_STRUCTURE_UPDATE is used to fix
incompatibility issue caused by ACPI_CPU_DATA structure update. It will
be removed after all the platform code uses new ACPI_CPU_DATA structure.
