Core db aristo hasher profiling and timing improvement (#1938)
* Explicitly use shared `Kvt` table on `Ledger` and `Clique` lookup.

why:
  Speeds up lookup time with `Aristo` backend. For writing `Clique` data,
  the `Companion` model allows to write `Clique` data past the database
  locked by evm transactions.

* Implement `CoreDb` profiling with API tracking

why:
  Chasing time spent per APT procs ...

* Implement `Ledger` profiling with API tracking

why:
  Chasing time spent per APT procs ...

* Always hashify when commiting or storing

why:
  A dirty cache makes no sense when committing

* Make sure that a zero key is created when adding/updating vertices

why:
  This is an error fix mainly for edge cases. A typical error was
  that the root key got deleted when there were only a few vertices
  left on the DB.

* Need all created and changed vertices zero-keyed on the cache

why:
  A zero key (i.e. empty Merkle hash) indicates that a vertex key
  needs to be updated. This would not be needed immediately after
  a merge as there is an actual leaf path on the cache layer. But
  after subsequent merge and delete operations this information
  might get blurred.

* Re-org hashing algorithm

why:
  Apart from errors, the previous implementation was too slow for
  two reasons:
  + some control hashes were calculated for debugging (now all
    verification is done in `aristo_check` module)
  + the leaf paths stored on the cache are used to build the
    labelling (aka hashing) schedule; there paths were accumulated
    over successive hash sessions although it is clear that all
    keys were generated, already
