fix(l1): fcu not triggering sync if snap is enabled + re-enable snap sync hive test

[fmoletta]

Motivation
PR #2426 changed how fork choice & new payload interact with the syncer and also introduced a bug. If snap sync is enabled, then fork choice update will never attempt to trigger a sync, so the sync process never gets started.
This PR fixes the bug and also refactors the sync manager api to better suit the new use cases

• Combine commonly used together SyncManager methods set_head & start_sync into sync_to_head
• Remove unused SyncManager method status and associated struct
• Make sure sync is triggered during fcu when needed even if snap sync is enabled
• Re-enable snap sync hive test suite
  Description

Closes #2521

nice catch!

Great that now the syncer decides to start the sync!
