cr50: add marshaling/unmarshaling of vendor commands and process turn_on

The upcoming CR50 firmware changes will require the AP to turn on the
previously downloaded CR50 firmware updates. A new vendor command
(TPM2_CR50_SUB_CMD_TURN_UPDATE_ON) is used for that. The command
accepts one parameter - the timeout before CR50 resets the system in
case there was an enabled update. The command also returns a value,
which indicates to the host if the update was turned on and the reboot
is coming.

This patch also adds more formal vendor command
marshaling/unmarshaling to make future additions easier.

BRANCH=gru,reef
BUG=b:35580805
TEST=with the actual user of this code in the next patch verified that
     the cr50 update is enabled as expected.
