Refactored and Optimized Query Cache with PgSQL Support

* Added Query Cache Support for PgSQL:

	* Introduced new variables for PgSQL Query Cache management:
		* pgsql-query_cache_size_MB
		* pgsql-query_cache_soft_ttl_pct
		* pgsql-query_cache_stores_empty_result
		* pgsql-query_cache_handle_warnings (not yet utilized)
	* Overwriting Transaction Status:
		* Sending current transaction state to the client when a result is
 returned from the query cache.
		* This currently does not differentiate between normal and error
transaction states—both are treated as active transaction states.

* Cache Lifetime Management:
	Replaced manual reference counting with std::shared_ptr to efficiently manage the lifecycle of cache entries,
ensuring proper memory deallocation and reducing complexity.

* Unified Purging Logic:
	Refactored the query cache purging logic to use a single thread for both
MySQL and PgSQL cache entries.

* Code Cleanup:
	Removed unnecessary methods and data members to streamline the codebase
and improve maintainability.

* Performance Optimization:
	Improved memory management, reducing memory footprint and enhancing
performance.
