Add PeerDAS KZG lib integration (construction & KZG verification) (#6212)

Browse Source 
* Add peerdas KZG library and use it for data column construction and cell kzg verification (#5701, #5941, #6118, #6179)

Co-authored-by: kevaundray <kevtheappdev@gmail.com>

* Update `rust_eth_kzg` crate to published version.

* Update kzg metrics buckets.

* Merge branch 'unstable' into peerdas-kzg

* Update KZG version to fix windows mem allocation.

* Refactor common logic from build sidecar and reconstruction. Remove unnecessary `needless_lifetimes`.

Co-authored-by: realbigsean <sean@sigmaprime.io>

* Copy existing trusted setup into `PeerDASTrustedSetup` for consistency and maintain `--trusted-setup` functionality.

* Merge branch 'unstable' into peerdas-kzg

* Merge branch 'peerdas-kzg' of github.com:jimmygchen/lighthouse into peerdas-kzg

* Merge branch 'unstable' into peerdas-kzg

* Merge branch 'unstable' into peerdas-kzg

* Load PeerDAS KZG only if PeerDAS is enabled.
