Make writes of `SchemaBatch`es atomic across `StateDb`'s `JmtNodes`, `JmtValues`, and `NativeDb`'s accessory state

[neysofu]

Summary

Our writes to StateDb are not fully atomic as our SchemaBatch writes tend to be isolated to a single column family, even when the write operation should arguably be atomic across multiple column families. The same holds for NativeDb. We should change the SchemaBatch API to allow atomic writes across several column families.
