Issue#3370223: Do not store language mapping as entity returns all the fields, including all translations variations (this could be further optimized)

Related to #3370223

While the changes in MR 37 makes good improvements, I found that on large sites it doesn't fully address all performance issues, particularly with cache invalidation and static caching. I added some suggested additional optimizations in a new MR:

• Utilizes Drupal's cache tag system more effectively, ensuring proper invalidation without explicit cache clearing.
• Implements a 12-hour TTL instead of permanent caching to prevent cache bloat.
• Recursively collects entity IDs from all menu levels, reducing the number of database queries.
• Implements static caching for processed trees, preventing redundant processing.
• Preserves and enhances cache metadata, (crucial for proper cache invalidation and variation)
• Optimizations result in fewer database queries, particularly for deep menu structures of 1000+ links
