From: IanX Kuo <ianx.kuo@intel.com>

First change
1. MdePkg/BaseLib: Add QuickSort function

It need to seperate to second change
2. MdeModulePkg/SortLib: Use QuickSort instead of QuickSortWorker
3. CryptLib/CryptLib: Remove duplicate QuickSortWorker
4. CpuCacheInfoLib: Remove MdeModulePkg dependenc
