This reverts commit 6693f359b3c213513c5096a06c6f67244a44dc52.. 678f85131238622e576705117e299d81cff755c9. Python3 migration is the fundamental change. It requires every developer to install Python3. Before this migration, the well communication and wide verification must be done. But now, most people is not aware of this change, and not try it. So, Python3 migration is reverted and be moved to edk2-staging Python3 branch for the edk2 user evaluation.
