x86/sched: Add the SD_ASYM_PACKING flag to the die domain of hybrid processors

Intel Meteor Lake hybrid processors have cores in two separate dies. The
cores in one of the dies have higher maximum frequency. Use the SD_ASYM_
PACKING flag to give higher priority to the die with CPUs of higher maximum
frequency.
