FSP will support both API and DISPATCH mode and require one field from Global Data Structure to tell which mode is selected by boot loader. Use one reserved byte for FSP API mode indicator - FspApiModeEnabled and maintain backward compatibility: 1. If platform FSP supports DISPATCH mode, it must initialize this new field. 2. If platform FSP does not support DISPATCH mode, this new field has no effect/not used. Test: Verified compiling without issue.
