In order to support secure boot with authenticated type variable store
and non secure boot with normal type variable store, add one flag to
switch them.
User can append '-D VPD_AUTHENTICATED_VARIABLE_STORE' to build command
to enable authenticated type varaible store.
Also, user can add 'VPD_AUTHENTICATED_VARIABLE_STORE = TRUE/FALSE' to the
defines section of Dsc file to switch authenticated/normal type variable
store.
VPD_AUTHENTICATED_VARIABLE_STORE is a new reserved key word for this function.
