Cr50: Add logging functionality to PinWeaver.
In order to be able to recover from the AP and Cr50 getting out of
sync, this logging functionality gives Cr50 a way to track the
state changes of the merkle tree so that the AP can be updated to
the current state as long as it has a recent enough copy.
This involves packing the important information so it can be stored
efficiently on flash, and adding the necessary messages for the
replay.
