Add support for meta parameter in listTools method.

McpSchema.PaginatedRequest now has a meta field (added in #344), but the client API methods don't expose it. As a result, servers which can accept the meta parameter in list tools cannot be used with java client. The Python SDK already supports passing _meta in tools/list requests:

This change aligns the Java SDK with the Python SDK and the MCP spec which allows _meta in PaginatedRequestParams.
