Implement a way to retrieve the MEV reward without looking at logs

[AlexSSD7]

Rationale

Right now, the only way to understand what MEV reward was received is to look for it manually inside the mev-geth logs. This method of data retrieval doesn't scale and is not really an idiomatic way. What I propose is to store each MEV block reward in the database, and make it retrievable remotely via RPC.

Implementation

Ideally, the MEV block reward should be accessible via these two options:

1. eth_getBlock request -> contains mevReward field.
2. mev_getReward RPC method -> returns the MEV reward for specific block. (I like this option more)

Also, it is crucial to have the correct reward recorded across all network nodes. This will require not just logging the reward on the mining node, but also implementing a standardized network-wide way to know the MEV reward of the block, so the MEV reward can be synced.

Thank you for the suggestion!

We've discussed how we could do this but have not found any quick fix that would make it possible to isolate mevReward from other fees. This is something we will add to our long term roadmap.
