refactor: Restructure MCP server auto-configuration modules for better modularity

This commit reorganizes the Spring AI MCP (Model Context Protocol) server auto-configuration modules to improve separation of concerns and modularity:

**Module Restructuring:**
- Rename  spring-ai-autoconfigure-mcp-server  →  spring-ai-autoconfigure-mcp-server-common ,  spring-ai-autoconfigure-mcp-server-sse
- Rename  spring-ai-autoconfigure-mcp-streamable-server-*  →  spring-ai-autoconfigure-mcp-server-streamable-*
- Rename  spring-ai-autoconfigure-mcp-stateless-server-*  →  spring-ai-autoconfigure-mcp-server-stateless-*

**New Common Modules:**
- Extract  spring-ai-autoconfigure-mcp-server-properties  for shared configuration properties
- Create  spring-ai-autoconfigure-mcp-server-common  for shared auto-configuration logic between STDIO, SSE and Streamable-HTTP servers

**Key Changes:**
- Move  McpServerProperties  and related properties classes to dedicated properties module shared with all server modules.
- Extract  McpServerChangeNotificationProperties  and  McpServerStreamableHttpProperties
- Refactor auto-configuration classes to use common base configurations
- Update package names from  *.autoconfigure  to  *.common.autoconfigure.properties
- Consolidate tool callback converter logic into common module

**Configuration Updates:**
- Separate SSE-specific properties from general server properties
- Improve conditional configuration with new condition classes
- Update dependency references across all affected modules and starters
- Maintain backward compatibility for existing property configurations

**Impact:**
- Better separation between different MCP server transport mechanisms (SSE, Streamable HTTP, Stateless)
- Reduced code duplication across auto-configuration modules
- Cleaner dependency management and module boundaries
- Improved maintainability and extensibility for future MCP server features

All existing functionality is preserved while providing a more modular and maintainable architecture for MCP server auto-configuration.
