Due to subtle differences between Bytes32 and UInt256 the changes failed

The current internal storage APIs implement UInt256 rather than Bytes32,
which is an accident of prior EVM design. This migrates all internal
handling of storage addresses and values to Bytes32.
The main performance gain is reduced GC pressure, in that UInt256
stores the data as an array of ints, whereas Bytes32 keeps a sliced or
wrapped array of bytes. Since database APIs are all byte array based
this should remove unneeded conversions when going to/from the DB.

* Backward Sync is now remembering recent finalized blocks.
When syncing using BWS we now consider finalized blocks reported by consensus layer.
When no finalized block is specified, nothing strange will go on. When Finalized block is specified
But Besu is not aware of any finalized block yet, we will sync as usual until the finalized block is about to get imported.
A new invariant is introduced when importing blocks using BWS.
All imported blocks has to descent from latest finalized block or a TTD block if we did not finalize yet.
* Importing a finalized block updates the information in Besu Mutable Blockchain.
* It is no longer possible to import blocks into the blockchain below a previously finalized block when using BWS
* When a new finalized block gets announced while BWS is in progress and Besu already has it imported, the Mutable Blockchain gets updated, and the chain gets checked for possible pruning
* When trying to import blocks of equal height as newly announced finalized block, then only the new announced finalized block will be possible to import using BWS
* When importing a new block using BWS after finalized, we can now guarantee that the block descends from latest finalized block

Reasons:
- you may wish to query the blockchain using rpc before you start
processing
- you may wish to register a websocket e.g to listen for blocks

EIP-1702 account versioning was a candidate for the Istanbul hard fork
but was removed prior to the first testnet. Other versioning techniques
have greater core dev mind share and one preparatory step landed in
London, EIP-3541, making EIP-1702 very unlikely to make it to Mainnet.

Since the EIP-1559 transition is going away, simply use a set of

Don't assume that there are two transaction types and instead check
what type the transactions are.

This is a not-fully-functional prototype of Bonsai Tries.
Bonsai tries is a flat leaf storage, branch-by-location, and diff based reorgs
refactoring of the existing forest based trie storage mechanism aimed at
creating sustainable performance at mainnet loads.
* Since it is experimental a feature flag of --Xdata-storage-format=BONSAI
controls activation.
Some required changes have a long reach:
* To accommodate location based storage many Trie operations accept both a
location and hash value. Each data storage format is keyed off of only
one of the fields, so many tests will pass in null to the other field.
* MutableWorldStateUpdater.persist now takes an argument of a block hash.
If this is a natural progression of blocks the hash of the new block is
passed in. Otherwise null should be passed in.

This implements the encoding/decoding logic and because it's backwards
compatible we can introduce it immediately. You can see that some of
the typed-transaction specific encoding/decoding logic is tested where
there are EIP-1559 encoding/decoding tests but there'll be more tests
included in the EIP-2930 PR.
