## Issue Addressed
#4118
## Proposed Changes
This PR introduces a "progressive balances" cache on the `BeaconState`, which keeps track of the accumulated target attestation balance for the current & previous epochs. The cached values are utilised by fork choice to calculate unrealized justification and finalization (instead of converting epoch participation arrays to balances for each block we receive).
This optimization will be rolled out gradually to allow for more testing. A new `--progressive-balances disabled|checked|strict|fast` flag is introduced to support this:
- `checked`: enabled with checks against participation cache, and falls back to the existing epoch processing calculation if there is a total target attester balance mismatch. There is no performance gain from this as the participation cache still needs to be computed. **This is the default mode for now.**
- `strict`: enabled with checks against participation cache, returns error if there is a mismatch. **Used for testing only**.
- `fast`: enabled with no comparative checks and without computing the participation cache. This mode gives us the performance gains from the optimization. This is still experimental and not currently recommended for production usage, but will become the default mode in a future release.
- `disabled`: disable the usage of progressive cache, and use the existing method for FFG progression calculation. This mode may be useful if we find a bug and want to stop the frequent error logs.
### Tasks
- [x] Initial cache implementation in `BeaconState`
- [x] Perform checks in fork choice to compare the progressive balances cache against results from `ParticipationCache`
- [x] Add CLI flag, and disable the optimization by default
- [x] Testing on Goerli & Benchmarking
- [x] Move caching logic from state processing to the `ProgressiveBalancesCache` (see [this comment](https://github.com/sigp/lighthouse/pull/4362#discussion_r1230877001))
- [x] Add attesting balance metrics

## Issue Addressed
Addresses #4234
## Proposed Changes
- Skip withdrawals processing in an inconsistent state replay.
- Repurpose `StateRootStrategy`: rename to `StateProcessingStrategy` and always skip withdrawals if using `StateProcessingStrategy::Inconsistent`
- Add a test to reproduce the scenario

## Issue Addressed
NA
## Proposed Changes
Similar to #4181 but without the version bump and a more nuanced fix.
Patches the high CPU usage seen after the Capella fork which was caused by processing exits when there are skip slots.
## Additional Info
~~This is an imperfect solution that will cause us to drop some exits at the fork boundary. This is tracked at #4184.~~

## Issue Addressed
Cleans up all the remnants of 4844 in capella. This makes sure when 4844 is reviewed there is nothing we are missing because it got included here
## Proposed Changes
drop a bomb on every 4844 thing
## Additional Info
Merge process I did (locally) is as follows:
- squash merge to produce one commit
- in new branch off unstable with the squashed commit create a `git revert HEAD` commit
- merge that new branch onto 4844 with `--strategy ours`
- compare local 4844 to remote 4844 and make sure the diff is empty
- enjoy

* Modify comment to only include 4844
Capella only modifies per epoch processing by adding
`process_historical_summaries_update`, which does not change the realization of
justification or finality.
Whilst 4844 does not currently modify realization, the spec is not yet final
enough to say that it never will.
* Clarify address change verification comment
The verification of the address change doesn't really have anything to do with
the current epoch. I think this was just a copy-paste from a function like
`verify_exit`.
* Add extra encoding/decoding tests
* Remove TODO
The method LGTM
* Remove `FreeAttestation`
This is an ancient relic, I'm surprised it still existed!
* Add paranoid check for eip4844 code
This is not technically necessary, but I think it's nice to be explicit about
EIP4844 consensus code for the time being.
* Reduce big-O complexity of address change pruning
I'm not sure this is *actually* useful, but it might come in handy if we see a
ton of address changes at the fork boundary. I know the devops team have been
testing with ~100k changes, so maybe this will help in that case.
* Revert "Reduce big-O complexity of address change pruning"
This reverts commit e7d93e6cc7cf1b92dd5a9e1966ce47d4078121eb.
## Proposed Changes
Clippy 1.67.0 put us on blast for the size of some of our errors, most of them written by me ( 👀 ). This PR shrinks the size of `BeaconChainError` by dropping some extraneous info and boxing an inner error which should only occur infrequently anyway.
For the `AttestationSlashInfo` and `BlockSlashInfo` I opted to ignore the lint as they are always used in a `Result<A, Info>` where `A` is a similar size. This means they don't bloat the size of the `Result`, so it's a bit annoying for Clippy to report this as an issue.
I also chose to ignore `clippy::uninlined-format-args` because I think the benefit-to-churn ratio is too low. E.g. sometimes we have long identifiers in `format!` args and IMO the non-inlined form is easier to read:
```rust
// I prefer this...
format!(
"{} did {} to {}",
REALLY_LONG_CONSTANT_NAME,
ANOTHER_REALLY_LONG_CONSTANT_NAME,
regular_long_identifier_name
);
// To this
format!("{REALLY_LONG_CONSTANT_NAME} did {ANOTHER_REALLY_LONG_CONSTANT_NAME} to {regular_long_identifier_name}");
```
I tried generating an automatic diff with `cargo clippy --fix` but it came out at:
```
250 files changed, 1209 insertions(+), 1469 deletions(-)
```
Which seems like a bad idea when we'd have to back-merge it to `capella` and `eip4844` 😱
