test(simulated): Add Simulation Tests for Malicious Proposer, Crashed EL and Malicious Consensus Majority (3/4)

[rezbera]

This PR builds on #2521 which needs to be merged first

This PR increases test coverage by adding the following tests:

• TestFinalizeBlock_BadBlock_Errors effectively serves as a test for how a valid node would react to a malicious consensus majority agreeing to a block with an invalid EVM transaction.

• TestProcessProposal_InvalidTimestamps_Errors effectively serves as a test for how a valid node would react to a malicious proposer attempting to use a future timestamp in the block that does not match the consensus timestamp.

• TestProcessProposal_CrashedExecutionClient_Errors effectively serves as a test for how a valid node would react to a valid block being proposed but the execution client has crashed.

it also moves the tests to different files based on logical separation
