internal/ethapi: handle blobs in API methods (#28786)

EIP-4844 adds a new transaction type for blobs. Users can submit such transactions via `eth_sendRawTransaction`. In this PR we refrain from adding support to `eth_sendTransaction` and in fact it will fail if the user passes in a blob hash.

However since the chain can handle such transactions it makes sense to allow simulating them. E.g. an L2 operator should be able to simulate submitting a rollup blob and updating the L2 state. Most methods that take in a transaction object should recognize blobs. The change boils down to adding `blobVersionedHashes` and `maxFeePerBlobGas` to `TransactionArgs`. In summary:

- `eth_sendTransaction`: will fail for blob txes
- `eth_signTransaction`: will fail for blob txes

The methods that sign txes does not, as of this PR, add support the for new EIP-4844 transaction types. Resuming the summary:

- `eth_sendRawTransaction`: can send blob txes
- `eth_fillTransaction`: will fill in a blob tx. Note: here we simply fill in normal transaction fields + possibly `maxFeePerBlobGas` when blobs are present. One can imagine a more elaborate set-up where users can submit blobs themselves and we fill in proofs and commitments and such. Left for future PRs if desired.
- `eth_call`: can simulate blob messages
- `eth_estimateGas`: blobs have no effect here. They have a separate unit of gas which is not tunable in the transaction.
