drivers/intel/fsp2_0: Add support for MP services2 PPI

Add support for MP services2 PPIs, which is slight modification
over MP services 1 PPIs. A new API StartupAllCPUs have been added
to allow running a task on BSP and all APs. Also the EFI_PEI_SERVICES
parameter has been removed from all MP PPI APIs.

This implementation also selects the respective MP services PPI version
supported for SoCs
