feat: implement EIP-7691 increase blob throughput (#7309)

* Init

* Add reqresp v2 definition

* Update validateGossipBlock

* Partial commit

* Reqresp. Add todos

* polish

* Fork-aware requestSszTypeByMethod

* Fixed minimal constants

* Bump config test version

* Update blob sidecar subnet computation

* Pass proper commitment limit to block gossip error

* Update blob sidecar index check

* Lint

* Update kzg unit test

* Subscribe to correct number of blob sidecar subnets

* Refactor constants getter to constantsHelper

* address comment

* Pass fork as first arg

* Update packages/state-transition/src/block/processExecutionPayload.ts

* refactor: move helper to get max blobs per block to fork config (#7322)

* Simplify type cast
