feature(trie): create rawDB trieDB engine

[MaksymMalicki]

This PR should be reviewed after #3017.
It introduces rawDB engine for the trie2, which is used by the new state. In this PR:

• The new package with rawDB is created. The structure of the package is quite simple and follows the pattern of pathdb and hashdb both in structure and interfaces.
• Contract, Class and Contract Storages are written directly to the pebbleDB and read directly from it. The writing is done in the Update() method, which takes the nodesets generated by trie2.Commit(), flattens them and writes them to the DB. For reading, the readNode() method was introduced.
• For the new State, Juno defaults to rawdb as a triedb engine

Next PR to review: #3278
