[Feature] Move kzg validation to blobtransaction sidecar

[mattsse]

Component

consensus, eips, genesis

Describe the feature you would like

currently blob validation is part of the 4844 tx:

alloy/crates/consensus/src/transaction/eip4844.rs

Lines 436 to 440 in 44b8a6d

	pub fn validate_blob(
	&self,
	sidecar: &BlobTransactionSidecar,
	proof_settings: &KzgSettings,
	) -> Result<(), BlobTransactionValidationError> {

it would be more useful to have the impl as a function on the sidecar:

pub fn validate(
        &self,
        versioned_hashes: &[B256],
        proof_settings: &KzgSettings,
    ) -> Result<(), BlobTransactionValidationError> {

this way it becomes reusable

the tx4844 impl then simply calls this will its versioned hashes and the given settings.
