feat(state-keeper): Parallel l2 block sealing (#1801)

## What ❔

L2 block data (tx results, storage logs, events, l2 to l1 logs, factory
deps, tokens) is sealed in parallel using concurrent DB connections. L2
block header is inserted after all l2 block data is inserted and serves
as a marker that l2 block is sealed. DB queries are adjusted so L2 block
is not accessed before block is sealed. Note, that some of the queries
are only queried for resolved block range, i.e. caller never tries to
access "pending" data. I haven't adjusted such queries on purpose to
keep their performance the same.

## Why ❔

Improves L2 block sealing performance
