fix(executor): Holocene EIP-1559 params in Header

[clabby]

Overview

Fixes the inclusion of the current block's base fee parameters within the Header. As-is, it always includes the payload attributes' EIP-1559 parameters in the header, but this is not the desired result.

Instead, we should be including the EIP-1559 parameters that were selected for the block. That is, if the parent header's nonce field is B64::ZERO, we should be including the canyon base fee parameters in the Header, not what was sent through the PayloadAttributes.

In addition, the attributes builder must send a zero'd out EIP1559params in the payload if the SystemConfig does not yet have a view of the EIP-1559 params.

Good catch!
