soc/intel/adl: Disable FSP debug output if !FSP_ENABLE_SERIAL_DEBUG 

This patch binds all FSP-M and FSP-S UPDs required for serial
redirection with `FSP_ENABLE_SERIAL_DEBUG` config to allow coreboot to
choose when to enable FSP debug output redirection to serial port.
For example:
PcdSerialDebugLevel => For controlling FSP debug level between FSP-M/S
SerialDebugMrcLevel => For controllig MRC debug level.

With this change FSP debug output will only be enabled when the user
enables `FSP_ENABLE_SERIAL_DEBUG` from site-local config with coreboot
serial image.

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