Implement statistical-based evaluation and metrics calculation

[silvanocerza]

As outlined in proposal #5794 we need to implement evaluation and metrics calculation for Haystack 2.x.

To complete this epic we need to close the following issues:

@silvanocerza I have opened a draft PR (#6464) that adds Evaluation and Metrics calculation for components and Pipelines. Requesting comments on the overall approach. Thanks.
