ArmPlatformPkg/PrePi: Add support for PrePi module

This module should handle the Pre PI phase before the DXE core is executed when there is no PEI Core support. It declares the required information needed by the DXE core through HOBs. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11949 6f19259b-4bc3-4df7-8a09-765794883524
