ArmPlatformPkg/MemoryInitPei: Generate a library from the PEI Module

In the aim to reuse the memory init features in a PrePi module (use to skip the PEI Core), this module has been divided into two files: - MemoryInitPeiLib: declare the memory HOBs - MemoryIniPeim: PEIM warpper for the library git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11950 6f19259b-4bc3-4df7-8a09-765794883524
