Refactor StateResolver to distinguish Object and Table

[pause125]

Maybe the StateResolver need to be refactor to:

pub trait StateResolver {
  // get object data from global state tree.
  fn resolve_object(&self, object: &ObjectID) -> Result<Option<Object>, anyhow::Error>;
  fn resolve_table(&self, handle: &ObjectID, key: &[u8]) -> Result<Option<State>, anyhow::Error>;
