Add DiceDrive::from_file factory method
This new function will be used in microdroid_manager to read the dice
chain written during first_stage_init for Microdroid VMs with microdroid
vendor partition.
This patch also adds a simple unit test to ensure that a dice chain read
from the file is equal to the one written to it.
