Actually support large contracts

[RogerPodacter]

Note

Plumbs a configured vm.Config (e.g., NoMaxCodeSize) into the miner and uses it for EVM execution during payload building for consistency with validation.

• Backend (eth/backend.go)
  • Builds a vm.Config (preimage/witness/tracer, NoMaxCodeSize) and passes it into miner.New.
• Miner (miner/miner.go, miner/worker.go)
  • Adds evmConfig to Miner; updates constructor to accept it.
  • Uses evmConfig when creating the EVM and applying transactions, aligning payload building with block validation (incl. beacon root processing).

Pull Request Overview

This PR modifies the miner to use a configurable EVM configuration instead of a hardcoded empty vm.Config{}, ensuring consistency between block building and block validation. This addresses potential gas accounting discrepancies that could arise from using different EVM configurations during these two operations.

• Added evmConfig field to the Miner struct to store the EVM execution configuration
• Updated miner.New() constructor to accept and initialize the evmConfig parameter
• Replaced hardcoded vm.Config{} instances in prepareWork and applyTransaction with the configured miner.evmConfig
