Builder flow for Deneb & Blobs (#4428)

* Add Deneb builder flow types with generics

* Update validator client `get_blinded_blocks` call to support Deneb

* `produceBlindedBlock` endpoint updates:
- Handle new Deneb BuilderBid response from builder endpoint (new BlindedBlobsBundle type)
- Build BlockContents response (containing kzg_commitments, proof and blinded_blob_sidecars)

* Appease Clippy lint

* Partial implementation of submit blinded block & blobs. Refactor existing `BlobSidecar` related types to support blinded blobs.

* Add associated types for BlockProposal

* Rename `AbstractSidecar` to `Sidecar`

* Remove blob cache as it's no longer necessary

* Remove unnecessary enum variant

* Clean up

* Hanlde unblinded blobs and publish full block contents

* Fix tests

* Add local EL blobs caching in blinded flow

* Remove BlockProposal and move associated Sidecar trait to AbstractExecPayload to simplify changes

* add blob roots associated type

* move raw blobs associated type to sidecar trait

* Fix todos and improve error handling

* Consolidate BlobsBundle from `execution_layer` into `consensus/types`

* Rename RawBlobs, Blobs, and BlobRoots

* Use `BlobRoots` type alias

* Update error message.
