Mount a filesystem on the crypt block device

Encryptedstore binary will format an ext4 fs (if required) in the crypt
device & mount it.

This patch also adds "ENCRYPTEDSTORE" as Partition type & formatting the
raw device with appropriate magic to identify this device is not yet
formatted with a filesystem.

Bug: 241541860
Test: Run a vm -> create a file
Test: Re-run the VM (with the same vm-instance) & check that it
persists.
