perf: optimize directory cache and animation initialization

[VanCZ1]

Summary

Optimized the logic of directory cache and animation initialization, significantly reducing loading time.

Core Changes

• Directory cache

• Remove the unused CachedModDirectory::entries.

• Add PrecacheAnimationHash() to replace PrecacheAnimationHashes(), avoiding repeated traversal.

• Add regularAnimationFiles in CacheAnimationFilesInDirectory(), avoiding repeated traversal.

• Directory parsing

• Capture cached CachedModDirectory and CachedLegacySubMod nodes by pointer, avoiding deep copying. Keep the shared lock on g_directoryCache.cacheLock held until the workerPool has finished.

• Animation initialization

• Add _animationPathToIndexMap to replace repeated linear scans in ReplacerProjectData::TryAddAnimationToAnimationBundleNames().

• Call SubMod::AddReplacerProject() and SubMod::SortReplacementAnimationsByPath() in subModsToUpdate rather than after every insertion.

• Call SubMod::InitializeReplacementAnimation() for every insertion, avoiding repeated traversal in subModsToUpdate, and use Utils::ComparePaths() to keep the path-matching behavior of SubMod::LoadReplacementAnimationDatas().

Testing

• Built on Windows and tested in-game.
• Performed cold-start testing and recorded the timing data.
