DONT MERGE: Change store chain-id for eth-* compoenents

[StanislavBreadless]

What ❔

1. Make eth watch track its state in a separate table
2. Make eth_sender track chain id for transactions so that nonce is fetched on per-chain-id basis

Note that it is breaking for ENs due to some fields being removed and breaking serde encoding. Thus, this PR should be merged first
