Add Engine API method stubs for the Amsterdam fork (Gloas on CL side):
- engine_newPayloadV5 for Amsterdam payloads
- engine_getPayloadV6 for Amsterdam payloads
- engine_newPayloadWithWitnessV5 for witness generation
- engine_executeStatelessPayloadV5 for stateless execution
- Update engine_forkchoiceUpdatedV3 to accept Amsterdam payloads
- Add PayloadV4 constant for ExecutionPayloadV4
This is a minimal implementation with method stubs only - no blockAccessList
(EIP-7928) integration yet.

The upstream libray has removed the assembly-based implementation of
keccak. We need to maintain our own library to avoid a peformance
regression.

I recently went on a longer flight and started profiling the geth block
production pipeline.
This PR contains a bunch of individual fixes split into separate
commits.
I can drop some if necessary.
Benchmarking is not super easy, the benchmark I wrote is a bit
non-deterministic.
I will try to write a better benchmark later

Implement standardized JSON format for slow block logging to enable
cross-client performance analysis and protocol research.
This change is part of the Cross-Client Execution Metrics initiative
proposed by Gary Rong: https://hackmd.io/dg7rizTyTXuCf2LSa2LsyQ
The standardized metrics enabled data-driven analysis like the EIP-7907
research: https://ethresear.ch/t/data-driven-analysis-on-eip-7907/23850
JSON format includes:
- block: number, hash, gas_used, tx_count
- timing: execution_ms, total_ms
- throughput: mgas_per_sec
- state_reads: accounts, storage_slots, bytecodes, code_bytes
- state_writes: accounts, storage_slots, bytecodes
- cache: account/storage/code hits, misses, hit_rate
This should come after merging #33522

The core part of this PR that we need to adopt is to move the code and
nonce change hook invocations to occur at tx finalization, instead of
when the selfdestruct opcode is called.
Additionally:
* remove `SelfDestruct6780` now that it is essentially the same as
`SelfDestruct` just gated by `is new contract`
* don't duplicate `BalanceIncreaseSelfdestruct` (transfer to recipient
of selfdestruct) in the hooked statedb and in the opcode handler for the
selfdestruct opcode.
* balance is burned immediately when the beneficiary of the selfdestruct
is the sender, and the contract was created in the same transaction.
Previously we emit two balance increases to the recipient (see above
point), and a balance decrease from the sender.

### Description
Add a new `OnStateUpdate` hook which gets invoked after state is
committed.
### Rationale
For our particular use case, we need to obtain the state size metrics at
every single block when fuly syncing from genesis. With the current
state sizer, whenever the node is stopped, the background process must
be freshly initialized. During this re-initialization, it can skip some
blocks while the node continues executing blocks, causing gaps in the
recorded metrics.
Using this state update hook allows us to customize our own data
persistence logic, and we would never skip blocks upon node restart.

In this PR, two things have been fixed:
---
(a) truncate the stale beacon headers with latest snap block
Originally, b.filled is used as the indicator for deleting stale beacon headers.
This field is set only after synchronization has been scheduled, under the
assumption that the skeleton chain is already linked to the local chain.
However, the local chain can be mutated via `debug_setHead`, which may
cause `b.filled` outdated. For instance, `b.filled` refers to the last head snap block
in the last sync cycle while after `debug_setHead`, the head snap block has been
rewounded to 1.
As a result, Geth can enter an unintended loop: it repeatedly downloads
the missing beacon headers for the skeleton chain and attempts to schedule the
actual synchronization, but in the final step, all recently fetched headers are removed
by `cleanStales` due to the stale `b.filled` value.
This issue is addressed by always using the latest snap block as the indicator,
without relying on any cached value. However, note that before the skeleton
chain is linked to the local chain, the latest snap block will always be below
skeleton.tail, and this condition should not be treated as an error.
---
(b) merge the subchains once the skeleton chain links to local chain
Once the skeleton chain links with local one, it will try to schedule the
synchronization by fetching the missing blocks and import them then.
It's possible the last subchain already overwrites the previous subchain and
results in having two subchains leftover. As a result, an error log will printed

This PR removes the legacy sidecar conversion logic.
After the Osaka fork, the blobpool will accept only blob sidecar version
1.
Any remaining version 0 blob transactions, if they still exist, will no
longer
be eligible for inclusion.
Note that conversion at the RPC layer is still supported, and version 0
blob
transactions will be automatically converted to version 1 there.
This PR fixes the bug reported in #33365.
The impact of the bug is not catastrophic. After a transaction is
ultimately fetched, validation and propagation will be performed based
on the fetched body, and any response with a mismatched type is treated
as a protocol violation. An attacker could only waste the limited
portion of victim’s bandwidth at most.
However, the reasons for submitting this PR are as follows
1. Fetching a transaction announced with an arbitrary type is a weird
behavior.
2. It aligns with efforts such as EIP-8077 and #33119 to make the
fetcher smarter and reduce bandwidth waste.
Regarding the `FilterType` function, it could potentially be implemented
by modifying the Filter function's parameter itself, but I wasn’t sure
whether changing that function is acceptable, so I left it as is.
This moves the tracking of the current syncmode into the downloader, fixing an
issue where the syncmode being requested through the engine API could go
out-of-sync with the actual mode being performed by downloader.
Fixes#32629

This improves the error code for cases where invalid query parameters
are submitted to `eth_getLogs`. I also improved the error message that
is emitted when querying into the future.
This is to benchmark how much the internal parts of GetBlobsV2 take.
This is not an RPC-level benchmark, so JSON-RPC overhead is not
included.

This PR introduces a new debug feature, logging the slow blocks with
detailed performance statistics, such as state read, EVM execution and
so on.
Notably, the detailed performance statistics of slow blocks won't be
logged during the sync to not overwhelm users. Specifically, the statistics
are only logged if there is a single block processed.
Example output

We still default to legacy txes for methods like eth_sendTransaction,
eth_signTransaction. We can default to 0x2 and if someone would like to
stay on legacy they can do so by setting the `gasPrice` field.

While updating to latest Geth, I noticed `OnCodeChangeV2` was not
properly handled in `SelfDestruct/6780`, this PR fixes this and bring a
unit test. Let me know if it's deemed more approriate to merge the tests
with the other one.
The periodic sealing loop failed to reset its timer when sealBlock
returned an error, causing the timer to never fire again and effectively
halting block production in developer periodic mode after the first
failure. This is a bug because the loop relies on the timer to trigger
subsequent sealing attempts, and transient errors (e.g., pool races or
chain rewinds) should not permanently stop the loop. The change moves
timer.Reset after the sealing attempt unconditionally, ensuring the loop
continues ticking and retrying even when sealing fails, which matches
how other periodic timers in the codebase behave and preserves forward
progress.
This PR removes dangling peers in `alternates` map
In the current code, a dropped peer is removed from alternates for only
the specific transaction hash it was requesting. If that peer is listed
as an alternate for other transaction hashes, those entries still stick
around in alternates/announced even though that peer already got
dropped.
This PR introduces two new metrics to monitor slow peers
- One tracks the number of slow peers.
- The other measures the time it takes for those peers to become
"unfrozen"
These metrics help with monitoring and evaluating the need for future
optimization of the transaction fetcher and peer management, for example i
n peer scoring and prioritization.
Additionally, this PR moves the fetcher metrics into a separate file,
`eth/fetcher/metrics.go`.
New RPC method eth_sendRawTransactionSync(rawTx, timeoutMs?) that
submits a signed tx and blocks until a receipt is available or a timeout
elapses.
Two CLI flags to tune server-side limits:
--rpc.txsync.defaulttimeout (default wait window)
--rpc.txsync.maxtimeout (upper bound; requests are clamped)
