soc/intel/meteorlake: Apply large cbmem buffer size for FSP debug

This patch ensures that the PRERAM_CBMEM_CONSOLE_SIZE and
CONSOLE_CBMEM_BUFFER_SIZE hold a larger cbmem buffer size to contain
the entire FSP debug serial log.

The existing implementation was not appropriate, where the larger cbmem
size was even applicable for serial AP firmware (w/o FSP debug) image
as well.

This change is necessary to ensure that the FSP debug serial log is
always available, even in cases where the cbmem buffer size is
limited.

BUG=b:280481298
TEST=Able to build and boot google/rex with non-FSP serial AP image
and with FSP serial AP image. Able to see the AP log completely inside
the cbmem.
