[Feature] embed consensus transaction types in eth_getTransaction

[mattsse]

Component

rpc

Describe the feature you would like

according to the spec https://ethereum.github.io/execution-apis/api-documentation/

eth_getTransaction returns the full transaction object

so we should be able to fully embed the consensus tx objects in the response object, like TxEnvelope

This likely requires manual serde, we could use the existing rpc::Transaction as the initial deserialize target and then do the conversion in deserialize internally, this is most likely the easiest solution because it should be more efficient than untagged.
