Produce block on main world state

[damian-orzechowski]

Changes DigestMessage implementation to produce block on main WorldState (not read-only) and then update BlockTree without re-processing block for validation.
Depends on: NethermindEth/nethermind#9388

Pull Request Overview

This PR modifies the DigestMessage implementation to produce blocks directly on the main WorldState instead of a read-only state, then updates the BlockTree without re-processing blocks for validation. The change simplifies block production by removing event-based validation and enabling a new BuildBlocksOnMainState configuration option.

Key changes:

• Adds BuildBlocksOnMainState configuration option to all Arbitrum config files
• Removes event-based block validation logic from ArbitrumRpcModule
• Introduces ArbitrumGlobalWorldStateBlockProducerEnvFactory to support building blocks on main state
