tss: Add new calls
- Local policy (non persistent) - recoveryOS - recoveryOS Local policy (persistent) The local policy TSS request differs slightly between the one for the restore process and the recoveryOS. The one for the restore process is meant to be used only once, and the one for the recovery os is meant to be loaded from disk, and thus has a different request. See the Ap,LocalBoot parameter.
