This is a spin-out from the EIP-4844 devnet branch, containing just the Engine API modifications
and nothing else. The newPayloadV3 endpoint won't really work in this version, but we need the
data structures for testing so I'd like to get this in early.

This change removes PoW header syncing related code from LES and also deletes 
duplicated packages les/catalyst, les/downloader and les/fetcher. These package copies
were created because people wanted to make changes in their eth/ counterparts, but weren't
able to adapt LES code to the API changes.

EIP-6780: SELFDESTRUCT only in same transaction

>     SELFDESTRUCT will recover all funds to the caller but not delete the account, except when called in the same transaction as creation

This updates the reference tests to the latest version and also adds logic
to process EIP-4844 blob transactions into the state transition. We are now
passing most Cancun fork tests.

It is usually best to set GOMAXPROCS to the number of available CPU cores. However, setting
it like that does not work well when the process is quota-limited to a certain number of CPUs.
The automaxprocs library configures GOMAXPROCS, taking such limits into account.

This changes the port mapping procedure such that, when the requested port is unavailable
an alternative port suggested by the router is used instead.

We now also repeatedly request the external IP from the router in order to catch any IP changes.

The struct logger (or opcode tracer) was missing the return data field even
if this was explicitly enabled by user via `"enableReturnData": true` in the config.
This PR fixes this issue.

This prevents an issue where the node would attempt to contact the bootstrap
nodes even if they weren't contained in the netrestrict list.

This change adds the ability to perform reads from freezer without size limitation. This can be useful in cases where callers are certain that out-of-memory will not happen (e.g. reading only a few elements). 

The previous API was designed to behave both optimally and secure while servicing a request from a peer, whereas this change should _not_ be used when an untrusted peer can influence the query size. 

This simplifies the code that initializes the discovery a bit, and
adds new flags for enabling/disabling discv4 and discv5 separately.

This change makes the StateDB track the state key value diff of a block transition.
We already tracked current account and storage values for the purpose of updating
the state snapshot. With this PR, we now also track the original (pre-transition) values
of accounts and storage slots.

Fixes an issue where waitgroups were used erroneously, which could lead to waitgroup being added to while wait was already invoked. 

Implements [EIP 5656](https://eips.ethereum.org/EIPS/eip-5656), MCOPY instruction, and enables it for Cancun.

Back before #27178 , we spun up a number of ethash verifiers to verify headers. So we also had tests to ensure that we were indeed able to abort verification even if we had multiple workers running.

With PR #27178, we removed the parallelism in verification, and these tests are now failing, since we now just sequentially fire away the results as fast as possible on one routine.

This change removes the (sometimes failing) tests

This PR adds metrics for p2p dialing, which gives us visibility into the quality of the dial 
candidates  returned by our discovery methods.

This change adds back the 'geth --dev' mode of operation, using a cl-mocker.

core (blockchain_test): add chain.Stop() to tests

This removes text parsing in leveldb metrics collection code. All metrics
can now be accessed through the stats API provided by leveldb.

We also add new gauge-typed metrics that count the number of tables at each level.
