UefiCpuPkg/CpuMpPei: Save/Restore CRx/DRx register for APs waking up
PeiStartupAllAPs()/PeiStartupThisAP() will send INIT-SIPI-SIPI to wakeup APs to
execute AP function. However, some registers will be reset after APs received
INIT IPI. We need to restore some registers (For example, CRx/DRx) manually
after APs wakeup.
