soc/intel/alderlake: Use coreboot native event handler for FSP-M/S 

This patch assigns FSP handler event for FSP-M and FSP-S with coreboot
romstage and ramstage debug handler when FSP_USES_CB_DEBUG_EVENT_HANDLER
Kconfig is enabled.

BUG=b:225544587
TEST=Able to build and boot brya. Also, verified the FSP debug log is
exactly same before and with this code change.
