Performance tracker

[mehdi-aouadi]

PR Description

Update the performance tracker to support the new Electra attestation aggregation logic.
This prevents a memory leak triggered in Electra.

Fixed Issue(s)

Fixes #8847

Documentation

• I thought about documentation and added the doc-change-required label to this PR if updates are required.

Changelog

• I thought about adding a changelog entry, and added one if I deemed necessary.

I run some benchmarks to compare the old and the new attestations performance algorithm and the results are encouraging.

Old Version

Phase0 Attestations

Benchmark                                                    (attestationsCount)   Mode  Cnt      Score     Error  Units

PerformanceTrackerBenchmark.calculateAttestationPerformance               100000  thrpt   10     10.397 ±   0.026  ops/s

Doesn't work for the electra attestations, so no Electra attestations benchmarking

Context:

• The operations refer to the calculateAttestationPerformance algorithm
• The attestationsCount is the number of attestations being processed. They are all attesting from the same slot and hence all aggregated (which is extreme)

Observations:

• The new algorithm performance is almost the same for the phase0 attestations
• The Electra attestations require almost twice the processing time but that's normal since the aggregation bit data structure is more complex. If we take into consideration that there are less attestations in Electra (more aggregation) this should be fine

we'll need to cherrypick this to the mekong branch too just remember...
