Slasher: Refactor and add tests (#13589)
* `helpers.go`: Improve naming consistency.

* `detect_attestations.go`: Improve readability.

* `receive.go`: Add `attsQueueSize` in log message.

* `checkSlashableAttestations`: Improve logging.

`avgBatchProcessingTime` is not displayed any more if not batch is
processed.

* `loadChunks`: Use explicit `chunkKind` and `chunkIndices`.

* `getChunk`: Use specific `chunkIndex` and `chunkKind`.

* `validatorIndicesInChunk` -> `validatorIndexesInChunk`.

* `epochUpdateForValidator`: Use explicit arguments.

* `getChunk`: Change order of arguments.

* `latestEpochWrittenForValidator`: Use `ok` parameter.

So the default value is not any more considered as the absence of
value.

* `applyAttestationForValidator`: Use explicit arguments.

* `updateSpans`: Use explicit arguments.

* `saveUpdatedChunks`: Use explicit arguments.

* `checkSurrounds`: Use explicit arguments.

We see here that, previously, in `checkSlashableAttestations`,
`checkSurrounds` was called with the default value of `slashertypes`: `MinSpan`.

Now, we set it expliciterly at `MinSpan`, which may explicit a bug.

* `epochUpdateForValidator`: Set modified by the function argument first.

* `applyAttestationForValidator`: Set mutated argument `chunksByChunkIdx`first.

* `applyAttestationForValidator`: Rename variables.

* `Test_processQueuedAttestations`: Fix test.

Two tests were actually exactly the same.

* `updateSpans`: Keep happy path in the outer scope.

Even if in this case the "happy" path means slashing.

* `checkSurrounds`: Rename variable.

* `getChunk`: Avoid side effects.

It adds a few lines for callers, but it does not modify any more
arguments and it does what it says: getting a chunk.

* `CheckSlashable`: Flatten.

* `detect_attestations_test.go`: Simplify.

* `CheckSlashable`: Add error log in case of missing attestation.

* `processQueuedAttestations`: Extract a sub function.

So testing will be easier.

* `processAttesterSlashings` and `processProposerSlashings`: Improve.

* `processAttesterSlashings`: Return processed slashings.

* `createAttestationWrapper`: Rename variables.

* `signingRoot` ==> `headerRoot` or `dataRoot`.

Before this commit, there is two typse of `signing root`s floating around.
- The first one is a real signing root, aka a hash tree root computed from an object root and
a domain. This real signing root is the object ready to be signed.
- The second one is a "false" signing root, which is actually just the hash tree root of an object. This object is either the `Data` field of an attestation, or the `Header` field of a block.

Having 2 differents objects with the same name `signing root` is quite confusing.
This commit renames wrongly named `signing root` objects.

* `createAttestationWrapper` => `createAttestationWrapperEmptySig`.

So it's clear for the user that the created attestation wrapper has an empty signature.

* Implement `createAttestationWrapper`.

* `processAttestations`: Return processed attester slashings.

* Test `processAttestations` instead of `processQueuedAttestations`.

By testing `processAttestations` instead of `processQueuedAttestations`, we get rid of a lot of tests fixtures, including the 200 ms sleep.

The whole testing duration is shorter.

* `Test_processAttestations`: Allow multiple steps.

* `Test_processAttestations`: Add double steps tests.

Some new failing tests are commented with a corresponding github issue.

* `NextChunkStartEpoch`: Fix function comment.

* `chunks.go`: Avoid templating log messages.

* `checkSlashableAttestations`: Simplify duration computation.
