ec/google/wilco: Add support for KB_ERR_CODE to Wilco EC
Adds support for the KB_ERR_CODE command on the Wilco EC. This command
is used to drive diagnostic LEDs on the platform after a failed boot.
This change also adds the Wilco EC mailbox command support to bootblock
and verstage so that those stages can use the KB_ERR_CODE command.
