Pull Request Overview

This PR refactors cache-related components to enable more precise invalidation of edge cache data while adding new tests for performance and correctness.

• Added and enhanced tests in VertexToEdgeLookupCacheTest.java to measure performance and validate cache invalidation logic.
• Introduced a new enum constant and method in HugeType.java to handle edge-vertex scenarios.
• Modified cache management and transaction logic in CachedGraphTransaction.java, VertexToEdgeLookupCache.java, and CacheManager.java to support finer invalidation of edge cache entries.
