Remove c-kzg (#8930)

Browse Source 
#7330


  Removes `c-kzg` from our `kzg` crate and rely fully on the `rust_eth_kzg` crate.

This removes the old `Blob` type entirely and instead handles `rust_eth_kzg::KzgBlobRef`s directly which allows us to avoid some extra stack allocations . Similarly, we make `Bytes32` and `Bytes48` type aliases rather than structs as this fits better with the new `rust_eth_kzg` API.
