fix: fix block value calculation in produceBlockV3

[ensi321]

Motivation

The previous PR #6136 it introduces consensusBlockValue and modifies the logic of determining using builder block vs execution block by comparing their values using the direct sum of executionPayloadValue and consensusBlockValue.

    const blockValueBuilder = builderPayloadValue + consensusBlockValueBuilder;
    const blockValueEngine = enginePayloadValue + consensusBlockValueEngine;
...
    if (blockValueEngine >= blockValueBuilder) {
      selectedSource = ProducedBlockSource.engine;
    } else {
      selectedSource = ProducedBlockSource.builder;
    }

This is incorrect because consensus block value is in Gwei while payload value is in Wei. Directly summing the two will result in payload value dominating the entire block value.

Description

• To convert consensus block value to Wei when calculating the total block value.
• Explicitly mention total block value is in Wei
• When logging consensus block value alone, the value should be in Gwei.

Caveat
There is an ongoing discussion in beacon API spec questioning the inconsistency of having different unit (Wei vs Gwei) in payload and CL block value. Will follow up if there is any related change to the spec.
