Michael Sproul 0f57fc9d8e Check slashability of attestations in batches to avoid sequential bottleneck (#8516)
Closes:

- https://github.com/sigp/lighthouse/issues/1914


  Sign attestations prior to checking them against the slashing protection DB. This allows us to avoid the sequential DB checks which are observed in traces here:
