Add MySQL exploration MCP tools with SQLite catalog

Implemented MCP (Model Context Protocol) server providing tools for
LLM-based MySQL database exploration:

- MySQL_Catalog: SQLite-based catalog for LLM external memory with
  upsert, get, search, list, merge, delete operations and FTS support

- MySQL_Tool_Handler: 17+ database exploration tools with guardrails:
  * Inventory: list_schemas, list_tables
  * Structure: describe_table, get_constraints, describe_view
  * Profiling: table_profile, column_profile
  * Sampling: sample_rows (max 20), sample_distinct (max 50)
  * Query: run_sql_readonly (max 200 rows, 2s timeout, SELECT-only)
  * Relationship: suggest_joins, find_reference_candidates
  * Catalog: catalog_upsert, catalog_get, catalog_search,
    catalog_list, catalog_merge, catalog_delete

- MCP Module Integration:
  * Added 6 new configuration variables for MySQL tool handler
    (mysql_hosts, mysql_ports, mysql_user, mysql_password,
     mysql_schema, catalog_path)
  * Added MySQL_Tool_Handler pointer to MCP_Threads_Handler
  * Implemented tool routing in MCP endpoint for tools/list,
    tools/describe, and tools/call methods

- TAP Tests: Updated to expect 14 MCP variables (was 8)

Add MCP (Model Context Protocol) module skeleton

Add new MCP module supporting multiple MCP server endpoints over HTTPS
with JSON-RPC 2.0 protocol skeleton. Each endpoint (/mcp/config,
/mcp/observe, /mcp/query, /mcp/admin, /mcp/cache) is a distinct MCP
server with its own authentication configuration.

Features:
- HTTPS server using existing ProxySQL TLS certificates
- JSON-RPC 2.0 skeleton implementation (actual protocol TBD)
- 5 MCP endpoints with per-endpoint auth configuration
- LOAD/SAVE MCP VARIABLES admin commands
- Configuration file support (mcp_variables section)

Implementation follows GenAI module pattern:
- MCP_Threads_Handler: Main module handler with variable management
- ProxySQL_MCP_Server: HTTPS server wrapper using libhttpserver
- MCP_JSONRPC_Resource: Base endpoint class with JSON-RPC skeleton
