cpu/intel/microcode: Avoid Pre-RAM microcode update if FIT enable

This patch changes the default behaviour of the MICROCODE_UPDATE_PRE_RAM
config for the platform with FIT (CPU_INTEL_FIRMWARE_INTERFACE_TABLE)
enabled. If FIT is enabled then microcode update will be taken care of
by FIT at pre-cpu reset hence, microcode update at pre-ram phase can be
skipped.

BUG=b:242473942
TEST=Able to build and boot google/rex with MICROCODE_UPDATE_PRE_RAM
remains disabled. No functional impact.

Without this patch:
  CONFIG_MICROCODE_UPDATE_PRE_RAM=y

With this patch:
  CONFIG_MICROCODE_UPDATE_PRE_RAM is not set
