it's step towards saving canonical and non-canonical bodies in same
table (and txs also in same own table). to reduce write amplification
(cheaper re-orgs)
PR change: reading BaseTxNum from existing snapshots instead of DB
DB will store in field body.BaseTxNum - non-canonical TxnID
Snapshots will store only canonical TxNum in field body.BaseTxNum

- always RLock all snapshots - to guarantee consistency
- introduce class View (analog of RoTx and MakeContext)
- move read methods to View object
- View object will be managed by temporal_tx

## What's this PR is about?
Minor fix in args usage message of support flag. The current message
says that the flag should be 'metrics.url' but it reality it should be
'metrics.urls'
Blob transactions are SSZ encoded, so it had to be added to decoding.
There are 2 encoding forms: `network` and `minimal` (usual). Network
encoded blob transactions include "wrapper data" which are `kzgs`,
`blobs` and `proofs`, and decoded by `DecodeWrappedTransaction`. For
previous types of transactions the network encoding is no different.
Execution-payloads / blocks use the minimal encoding of transactions. In
the transaction-pool and local transaction-journal the network encoding
is used.
Concerns:
1. Possible performance reduction caused by these changes, not sure if
streams are better then slices. Go slices in this modifications are
read-only, so they should be referred to the same underlying array and
passed by a reference.
2. If `DecodeWrappedTransaction` and `DecodeTransaction` will create
confusion and should be merged into one function.
This is the beginning of the series of changes to make it possible to
run multiple instances of erigon inside a single process (as devnet tool
does), with the logging from these processes going to respective log
files correctly.
This is the first part where the initial infrastructure is being
established

this first major move separates the transient beacon state cache from
the underlying tree.
leaf updates are enforced in the setters, which should make programming
easier.
all exported methods of the raw.BeaconState should be safe to call
(without disrupting internal state)
changes many functions to consume *raw.BeaconState in perparation for
interface
beyond refactor it also:
adds a pool for the leaves of the validator ssz hash
adds a pool for the snappy writers
removed the parallel hash experiment (high memory use)
