EVM: basic implementation of eth_sendRawTransaction

[bkolad]

Description

This PR introduces the following changes:

1. sov-etehreum crate in full-node. This crate provides eth_sendRawTransaction rpc endpoint. This endpoint wraps evm transaction in rollup transaction and sends it to celestia (the endpoint will be generic over DA in the future).
   Currently, the implementation is very basic. The logic panics if unexpected data is encountered, and some of the values in the request are hardcoded to defaults. Despite these limitations, it is sufficient for a simple unit test to function and will be improved in future pull requests.

2. Adds a couple of ethereum rpc endpoints in sov-evm/src/query.rs. Once again, the implementation is minimal and will be expanded upon in the next pull requests.
