Refactored Query Processor Architecture

- Introduced separate query processors for MySQL and PostgreSQL.
- Removed unnecessary GTID logic from `PgSQL_Session`.
- Added a command counter for PostgreSQL queries.
- Refactored `Query_Processor` to serve as a base class containing core
  functionalities applicable to both MySQL and PostgreSQL.

Changes:

- Removed GTID-related code from `PgSQL_Logger` and `PgSQL_Session`:
    - bool with_gtid;
    - char gtid_buf[128];
    - int gtid_hid;

- Added new PostgreSQL-specific tables:
    - `pgsql_query_rules`, `pgsql_firewall_whitelist_rules`,
      `pgsql_query_rules_fast_routing`
    - `runtime_pgsql_query_rules`,
      `runtime_pgsql_firewall_whitelist_rules`,
      `runtime_pgsql_query_rules_fast_routing`

- Added PostgreSQL-related variables:
       pgsql_thread___commands_stats
       pgsql_thread___query_digests
       pgsql_thread___query_digests_lowercase
       pgsql_thread___query_digests_no_digits
       pgsql_thread___query_digests_replace_null
       pgsql_thread___query_digests_normalize_digest_text
       pgsql_thread___query_digests_track_hostname
       pgsql_thread___query_digests_keep_comment
       pgsql_thread___query_digests_max_digest_length
       pgsql_thread___query_digests_max_query_length
       pgsql_thread___query_digests_grouping_limit
       pgsql_thread___query_digests_groups_grouping_limit
       pgsql_thread___enable_load_data_local_infile
       pgsql_thread___auditlog_filename
       pgsql_thread___auditlog_filesize
       pgsql_thread___eventslog_filename
       pgsql_thread___eventslog_filesize
       pgsql_thread___eventslog_default_log
       pgsql_thread___eventslog_format
       pgsql_thread___firewall_whitelist_errormsg
       pgsql_thread___firewall_whitelist_enabled
       pgsql_thread___query_processor_iterations
       pgsql_thread___query_processor_regex
