fix(lambda): validation for FunctionUrlCorsOptions.maxAge (#25495)

AWS::Lambda::Url's Cors.MaxAge has a maximum value of 86400 (secs)
see https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-lambda-url-cors.html#cfn-lambda-url-cors-maxage

This PR adds validation for it.

Note: No maximum value for S3, CloudFront (ResponseHeadersPolicy), and API Gateway.
