Users: Add caching to count_user_posts function

Browse Source 
Introduced caching for the `count_user_posts` function to reduce redundant database queries. This ensures better performance by storing and reusing query results when possible. Additionally, sanitized and sorted the `$post_type` array to avoid invalid queries.
