Add Gloas fork choice test for new validator deposit

[unnawut]

Description

Attempting to resolve the TODO in electra's test_new_validator_deposit_with_multiple_epoch_transitions

• Add test_new_validator_deposit_with_multiple_epoch_transitions() for Gloas, covering deposit processing through fork choice with reorgs, basically the same goal as Electra's test case but with support for execution payload commit & reveal
  • Added as a separate test rather than updating Electra's because it requires multiple branching: creating the execution requests with the deposit request, not having the deposit request in the block body, creating and applying the execution payload envelope. I think this way is more readable but tbh I'm not sure what's the best practice for this. Happy to change though.
• Move prepare_execution_payload_envelope() from the test case file to the helper file because it's now being used by both test_process_execution_payload.py and test_deposit_with_reorg.py
  • Again I'm not too familiar with the best practices in this repo. Happy to move it back but the import will be a bit counterintuitive to import function from another test case
• Update test/helpers/execution_payload.py:
  • Add reveal_payload_to_state() that prepares and processes the execution payload envelope
• Update test/helpers/attestations.py:
  • state_transition_with_full_block() accepts envelopes where if provided, it'll perform reveal_payload_to_state() after state transition
• Update test/helpers/fork_choice.py:
  • tick_and_add_block() accepts optional envelope and triggers on_execution_payload() if envelope provided
  • apply_next_slots_with_attestations() accepts with_payload_reveal so it knows to check store.payload_states if the flag is present
