perf: Move mutex to the partition level (#5486)

Browse Source 
This change introduces two key optimizations:
* Mutex scope reduction: Limits the lock to individual partitions within `TaggedCache`, reducing contention.
* Decoupling: Removes the tight coupling between `LedgerHistory` and `TaggedCache`, improving modularity and testability.

Lock contention analysis based on eBPF showed significant improvements as a result of this change.
