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

This patch assigns FSP handler event for FSP-S with coreboot ramstage
debug handler when FSP_DEBUG_EVENT_HANDLER_IN_COREBOOT Kconfig is
enabled.

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