Also: - Replace `impl From<LevmError> for EvmError` with an error mapping. - Remove duplicated `VmError`. - Rename `returndata` -> `return_data`.

**Motivation** <!-- Why does this pull request exist? What are its goals? --> We currently have an in-memory database that should soon be replaced by the node's in-disk database. For that purpose we want to allow us to switch between both kinds of databases. The need to implement this PR's features and refactor the `Db` arose while working on #904. **Description** <!-- A clear and concise general description of the changes this PR introduces --> This PR includes: - Adding a `Cache` to store warm accounts. This removes the need of having `accessed_accounts` and `accessed_storage_slots` sets in `Substate` because we know that if they are cached then they are warm. - Making our `Db` implement the `Database` trait and interact with it only using methods and not it's attributes, so in the future we can implement that trait for the actual node's database. - Fix call opcodes and remove delegate attribute from `CallFrame`. <!-- Link to issues: Resolves #111, Resolves #222 --> Part of #814. --------- Co-authored-by: Juani Medone <juan.medone@lambdaclass.com> Co-authored-by: maximopalopoli <mpalopoli@fi.uba.ar> Co-authored-by: Javier Chatruc <jrchatruc@gmail.com>
