Are calls to psa_connect/call/close allowed after `TZ_StoreContext_S()` has been called but before `TZ_LoadContext_S()` is called? If not, does that result in a panic or simply error return codes?

Is there a secure-side SPM API that can be invoked from a custom veneer function to determine if the SPM is in the zone between `TZ_StoreContext_S()` and `TZ_LoadContext_S()`?

Is there an API that returns the current MemoryId?
