Add timing for block availability (#5510)

* Add timing for block availability

* Attestation metrics analysis

* Prettier printing

* Add some metrics and timings to track late blocks

* Update to latest unstable

* fmt

* Merge latest unstable

* Small tweaks

* Try pushing blob timing down into verification

* Simplify for clippy
