1. delete Include/Guid/VariableInfo.h

2. move VariableFormat.h into GUID directory and change the “Signature” field of the VARIABLE_STORE_HEADER to gEfiVariableGuid value.
3. merging VARIABLE_INFO_ENTRY structure into the new Include/Guid/VariableFormat.h
4. change gEfiVariableInfoGuid into gEfiVariableGuid.
5. modify FDF files to use new guid value instead of the original signature.
6. all code related to signature is changed to use guid value.
