Move SmmLib from IntelFrameworkPkg to MdePkg because this library is useful to both Framework SMM and PI SMM implementations.
Add SMM CPU Save State Protocol defined in the Framework SMM CIS 0.91 Specification. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9841 6f19259b-4bc3-4df7-8a09-765794883524
