soc/intel/common/block/smm: Add `mainboard_smi_finalize`
This commit adds a method called `mainboard_smi_finalize` which provides
a mechanism for a mainboard to execute some code as part of the finalize
method in the SMM stage before SoC does its finalization.
BUG=b:191189275
BRANCH=None
TEST=Implement `mainboard_smi_finalize` on lalala and verify that the
code executes in SMM.
