core/state: access trie through Database interface, track errors (#14589)
With this commit, core/state's access to the underlying key/value database is mediated through an interface. Database errors are tracked in StateDB and returned by CommitTo or the new Error method. Motivation for this change: We can remove the light client's duplicated copy of core/state. The light client now supports node iteration, so tracing and storage enumeration can work with the light client (not implemented in this commit).
