  This function allocates pool for an EFI_HII_PACKAGE_LIST structure
  with additional space that is big enough to host all packages described by the variable 
  argument list of package pointers.  The allocated structure is initialized using NumberOfPackages, 
  GuidId,  and the variable length argument list of package pointers.

  Then, EFI_HII_PACKAGE_LIST will be register to the default System HII Database. The
  Handle to the newly registered Package List is returned throught HiiHandle.

  @param  NumberOfPackages  The number of HII packages to register.
  @param  GuidId                    Package List GUID ID.
  @param  HiiHandle                The ID used to retrieve the Package List later.
  @param  ...                          The variable argument list describing all HII Package.

  @return
  The allocated and initialized packages.
