https://bugzilla.tianocore.org/show_bug.cgi?id=4623
1.Added PeiCoreEntry.nasm, SecEntry.nasm and Stack.nasm for X64.
2.Made changes in common files to support both IA32 and X64.
3.Added the PCDs below for FSP-T UPD revisions and reset vector in FSP.
 - PcdFspWrapperResetVectorInFsp
 - PcdFspWrapperBfvforResetVectorInFsp
 - PcdFsptUpdHeaderRevision
 - PcdFsptArchUpdRevision
