Add PrintThunk driver, it depends on PrintLib on top of MdePkg:
1. If the library instance is BasePrintLib, it has no prerequisite to produce EDK print protocol 2. If the library instance mapping is DxePrintLibPrint2Protocol, it acts as PrintOnPrint2Thunk. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@7584 6f19259b-4bc3-4df7-8a09-765794883524
