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

Beginning FSP 2.2 specifications Fsps Config Upd "FspEventHandler"
was moved to Fsps Arch Upd. Hence we were not seeing Fsps Debug
log was not using coreboot debug library.

This change assigns Fspd Arch Upd FspEventHandler with coreboot
ramstage debug handler when FSP_USES_CB_DEBUG_EVENT_HANDLER
Kconfig is enabled.

Before:

Dumping FSPS_UPD - Size: 0x00001510
0x00000000: 0x41 0x44 0x4C 0x55 0x50 0x44 0x5F 0x53 0x02 0x00 0x00
0x00000010: 0x00

With the fix:

[SPEW ]  Dumping FSPS_UPD - Size: 0x00001528
[SPEW ]  0x00000000: 0x41 0x44 0x4C 0x55 0x50 0x44 0x5F 0x53 0x02
[SPEW ]  0x00000010: 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00
[SPEW ]  0x00000020: 0x01 0x00 0x00 0x00 0x20 0x00 0x00 0x00 0xAA
[SPEW ]  0x00000030: 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00
[SPEW ]  0x00000040: 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00

BUG=b:237263080
TEST=Able to build and boot MTL RVP, verified the FSP-S debug
log is using coreboot debug library.
