sandbox: tpm: Support storing device state in tpm2

At present the tpm2 emulator does not support storing the device state.
Add this so we can handle the normal vboot flow through the sandbox
executables (VPL->SPL etc.) with the TPM contents staying in place.

Note: sandbox has not yet been converted to use livetree for the state
information, since livetree does not yet support writing to the tree.
